Computer performance depends on the power of hardware components, and on properly configured work operating system. Little benefit from volume increase random access memory if it is full of useless programs. Powerful processor will not speed up the work if it is limited to save battery power. Tweaking Windows can significantly optimize system performance at no additional cost.
What affects system performance
The performance of Windows 7 is determined by many factors, some of which are the result of trade-offs between power, convenience, and battery life, and others of which depend on how well-groomed the computer is. Therefore, in order to increase performance, it is necessary to tune the system to maximum performance and remove all obstacles for its normal operation.
Maybe, experienced user wants to independently debug each element of the system and customize the computer to fit his needs. For the rest, the best solution would be to use special programs for fine tuning systems (tweakers) that show problems in a convenient and understandable way and help to eliminate them.
Optimization programs (free and paid)
There are many programs on the market whose main purpose is to improve the operation of Windows 7. There are universal large applications and small specialized utilities, programs with many customizable options and with one "red button". Most programs have additional functions, which are not directly related to performance, but are also important for the user, for example, the protection of personal data.
Universal
Usually, universal programs possess big set optimization utilities, but they are paid. Packages with limited functionality or outdated versions are distributed free of charge.
Advanced System Care
Universal Application Advanced System Care is an impressive set of tools for fine-tuning Windows, protection against malware, spyware and adware. Special utilities fix problems with the registry, security settings and operations with intermediate files. To date, the application is one of the best in this category.
The interface of Advanced SystemCare stands out from the background of other programs with a futuristic design. But at the same time, it remains simple, convenient and intuitive.
The free version of Advanced SystemCare also has good functionality, but the program's capabilities are truly revealed in the full paid package.
CCleaner
The popular CCleaner package primarily specializes in cleaning the operating system, drives and RAM, hence its name. But many other Windows 7 optimization features are available to the user.
The functionality of CCleaner is narrower than that of Advanced SystemCare, however, special cleaning utilities are much more powerful:
The package interface is very simple and intuitive, does not require deep knowledge of the system.
Free distribution of old CCleaner versions. To get more powerful upgrade packages, you will have to pay.
AusLogics BoostSpeed
The BoostSpeed package from AusLogics, a company with Australian roots, has an impressive set of utilities and a user-friendly interface. The stated main purpose of the package is to increase the speed of the system.
The functionality contains utilities for repairing the registry, system settings, and hard disk care:
The interface is friendly, convenient, typical for programs in this category:
To unlock all the features of the package, you will have to buy a paid version. Free has much less functionality.
Mini-programs for your computer or laptop
Small, compact, sometimes not even requiring installation programs usually have limited specialized functionality and are distributed free of charge. These two qualities make them a good addition to a versatile package.
SpeedUpMyPC
The SpeedUpMyPC package is positioned by the developer as a system accelerator. Cleaning up garbage and system errors is considered as part of the performance improvement procedures.
The functionality of SpeedUpMyPC contains utilities standard for this category of programs, as well as our own developments aimed at improving performance:
The package interface is original and colorful, quite convenient:
The program belongs to the category of shareware, offers a free limited version with the ability to add utilities for a fee.
Comodo System Cleaner
Another free app Comodo System Cleaner with a powerful set of cleaning utilities. The package also contains functionality to fix crashes and Windows errors, hard disk care.
The functionality of the package has a pronounced "shift" towards cleaning, but some utilities are related to the optimization of work by other methods.
The interface of Comodo System Cleaner is made in the usual "matrix" style, it is intuitive and simple:
An additional advantage of the app is that it is free.
Wise Registry Cleaner
A small, free, installation-free utility for optimal system tuning by cleaning the Windows registry.
The functionality of the package is focused on operations with the system registry:
Wise Registry Interface Cleaner simple and intuitive. 
Cleaning can be with different depths
The absolute advantage of the package is its free distribution.
Easy Cleaner
The free EasyCleaner program cleans the system of unnecessary information, fixes the Windows 7 registry and presents disk information in a convenient graphical representation.
The functionality of the package is a little poorer than that of CCleaner, but it has its own characteristics:
The program interface is very simple and clear, the design is classic:
Since the program is free, it can be a good addition to the universal package.
red button
Program developers red button In the first place put the simplicity and convenience of the interface. Even the name of the application is not accidental - you can start the optimization with one click on the big red button.
Red Button has a very good functionality, consisting of utilities that optimize the operation of the processor, RAM, hard drive and registry:
The program interface is very clear and simple, in the style of Windows 7 system services:
Until recently, the program was distributed free of charge, but the popularity of the package inspired the manufacturer to release paid versions. But past free modifications show good results.
Glary Utilities
small program Glary Utilities also claims to be universal, but its strength can be considered a system analysis toolkit.
The Glary Utilities functionality contains tools for checking and optimally configuring the system, privacy, caring for the hard drive, and updating existing drivers.
The application interface is friendly, very similar to the built-in system Windows utilities 7:
The somewhat limited functionality of the package is justified by the fact that it is distributed free of charge.
nCleaner
The nCleaner application, due to its small size and functionality, can be classified as a mini-program for optimizing the system. The main emphasis of the program is on cleaning.
The functionality of nCleaner is focused on removing unnecessary information, but there are also additional tools:
- Cleaning. Tools for cleaning the system, registry, personal data.
- Trash. A separate utility for finding and deleting intermediate and extra files. The modes of cleaning the main folders (faster) and scanning all disks (slower, but full) are preset.
- Optimization. Tools for optimal tuning of Windows and various services to increase the speed and stability of the computer.
- Autoload. Editing the list of automatically launched applications during Windows startup.
- Confidentiality. Deleting information with the impossibility of recovery and cleaning up unallocated hard disk space.
- Clearing RAM. A separate utility for unloading unused blocks from RAM.
The interface of the mini-program is very simple and clear:
- One page. The main functions are collected on home page which is very convenient.
- Schedule. It is possible to automatically run according to a user-specified schedule.
nCleaner lacks the traditional option to undo changes made or create backup copies of the system registry, which is justified given the small size of the application.
Of course, this mini-program is distributed free of charge.
Comparison table: which program to choose

As expected, the largest number of utilities necessary for optimizing the system operation is contained in universal packages. But mini-programs have their own strengths. They are more compact, easy to use, have advanced special features and, as a rule, are free.
Specialized programs greatly simplify the fine-tuning of Windows, automate optimization processes and work with many options. The user can easily choose the program for their own needs.
User question
Hello.
Tell me why my Windows 7 after installation works fine, everything opens and loads quickly. After 2-3 weeks - it seems to be replaced: the computer starts to boot for a long time, the conductor reacts reluctantly, all the work is somehow slowly going on.
Is it possible to optimize and speed up the system, without systematically reinstalling it, so that it works quickly, as after reinstalling the system?
Good day.
Pretty typical behavior of Windows, and, in itself, the seven is not to blame here, the same would be, for example, with the ten. The fact is that over time, a large amount of "garbage" accumulates in Windows (temporary files, cache, etc.), new programs register themselves at startup, all sorts of gadgets appear, etc. - all this begins to "eat" RAM, load the processor , the disk subsystem, which ultimately affects performance.
In this article I will give some of the most important recommendations to optimize and speed up the system. (by the way, I don’t consider options with an upgrade, for example, in the form of buying additional RAM sticks or an SSD drive) . So...
9 steps to fix lag and speed up your Windows 7 system
Description of the problem:
As I said above, over time, as programs are installed, some of them register themselves in Windows startup and start every time you turn on the computer. Everything would be fine, but some of these programs are quite demanding on resources and affect the PC boot speed, sometimes significantly.
I want to pay special attention to uTorrent. If you have a lot of torrents distributed and the program is in autoload, then Windows can load tens of seconds longer!
Solution:
Logical and simple - you need to open the startup settings and remove everything unnecessary and unnecessary from it. In general, in my opinion, in startup you need only those programs that you use absolutely every time you turn on your computer.
To view startup in Windows 7 - press the key combination WIN + R, then type the msconfig command and press Enter (example below).
By the way, special utilities can help you check Windows startup and remove unnecessary programs from your computer. One of these is CCleaner (example in the screenshot below). Quite convenient: to view the startup list in CCleaner, just open the menu.
Windows cleaners (including startup) -
SERVICES - WHICH CAN BE DISABLED
Description of the problem:
By default, Windows includes quite a lot of services that take up RAM and affect performance in one way or another (I should note that disabling "unnecessary" services is especially noticeable on low-power PCs with a small amount of RAM). For example, if you don't have fax- why do you need this running service, or print manager - if there is no printer?
Solution:
The optimization in this step is to disable those services that are not needed specifically on your PC. To disable any service, you need to open their list. To do this, press the keyboard shortcut WIN+R, enter services.msc, click OK.
Next, select a service from the list: its description appears on the left. To disable the service - open it by double-clicking the left mouse button (in my example, I chose Update centre ).
Then, in the "Startup type" column, set the option to "Disabled", and then click the "Stop" button. Thus, you will stop the service, and it will no longer start.
Important! Do not disable all services in a row, some of them are needed for the normal operation of the system. In any case, before making changes - read the description of the service, whether the meaning is clear. In general, (backup) - if suddenly something, calmly roll back ...
What services "can" be disabled in Windows 7:
- Windows Card Space;
- Windows Search;
- Offline files;
- Network Access Protection Agent;
- Adaptive brightness control;
- Windows Backup;
- Auxiliary service IP;
- Secondary login;
- Grouping network participants;
- Dispatcher automatic connections remote access;
- Remote Access Connection Manager (if there is no VPN);
- Network Member Identity Manager;
- Performance logs and alerts;
- Secure storage;
- Setting up a remote desktop server;
- Smart card deletion policy;
- Shadow Copy Software Provider (Microsoft);
- Homegroup listener;
- Windows Event Collector;
- Network login;
- Tablet PC input service;
- Windows Image Download Service (WIA) (if there is no scanner or camera);
- Service Windows Scheduler media center;
- Smart card;
- Volume shadow copy;
- Node of the diagnostic system;
- Diagnostic Service Host;
- Fax;
- Performance counter library host;
- Security Center;
- Center windows updates(I recommend turning it off for a while. And updating it manually, because in auto mode this service often creates a high load, which slows down the PC).
CLEARING GARBAGE FROM THE SYSTEM
Description of the problem:
No matter how carefully you use your Windows, anyway, over time, a large amount of garbage accumulates in it: old tails in the registry from a long time ago remote programs, temporary files left during the installation of some software, browser cache, etc. All these files, as they accumulate, begin to affect the performance of the system as a whole.
Sometimes, the user of such "garbage" accumulates for several tens of gigabytes!
Solution:
In order not to repeat here and not to paint how and what, I recommend that you read my instructions (the link is given just below).
How to clean your computer from garbage to speed up work -
UNNECESSARY VISUAL EFFECTS. GADGETS
Description of the problem:
Windows 7, in comparison with Windows XP, has become more beautiful: effects, shadows, Aero, etc. But all this affects the speed of the computer (very noticeable on weak machines).
The same problem can be gadgets(small windows on the desktop that can tell you about the weather, exchange rates, etc.). They appeared just in Windows 7 - and everyone began to actively use them. Meanwhile, they are quite demanding on the system...
Solution:
About gadgets- it is enough to close them, and they will disappear from the desktop (they will stop consuming your resources). It is also convenient to find out the same weather and exchange rates in the browser...
As for visual effects- then to configure them open the panel Windows controls by the address: Control Panel\System and Security\System.
In the "Advanced" tab, open the performance options (see screenshot below).
In the tab "Visual effects" uncheck those effects that you do not need. For maximum system acceleration - put the slider in the "Ensure the best performance" position. Next, save your settings.
The appearance may deteriorate somewhat, but the system will become much more responsive.
DRIVERS - IS EVERYTHING OK WITH THEM
Description of the problem:
Driver - driver strife! A lot depends on the version of the driver. For example, those drivers that are installed into the system along with Windows do not always work optimally (for example, Network Card may not work to all its capabilities (at a reduced speed), the driver for the video card cannot be configured at all, etc.).
In addition, your system may not have drivers installed at all for some of the equipment (as in the screenshot below). By the way, to see what equipment there is no driver for, open device Manager (key combination Win+R , then enter the command devmgmt.msc ).
There are no drivers for: video card, network controller, Ethernet controller, etc.
Solution:
- The best option is to download the drivers from your computer/laptop manufacturer's website. You can also use the driver disk that came with the PC upon purchase (if you have saved ☺). If you do not know your equipment, you can use.
- You can use . I have several articles on my site dedicated to them, one of the links is in front of you ...
- If possible: I recommend checking several versions of drivers at once (especially for a video card). It often happens that an older driver works better than a newer one.
POWER SETTINGS
Description of the problem:
This problem is typical for laptops, netbooks and other compact gadgets that run on batteries. The fact is that there are several modes of operation: economical (when at the expense of performance, the laptop saves energy for longer battery life), normal, and high performance. And by default, most often it is normal (balanced), or economical ...
Solution:
Choosing a power plan // Windows 7
For detailed power settings: first click the "Setting up a power plan" link (opposite the selected power mode), then at the bottom of the screen open the "Change advanced power settings" link. Next, you can open desired tabs and adjust each setting individually.
For example, it is often necessary to set up work hard drive(forbid it to stop), or adjust the brightness of the monitor (remove adaptability), etc.
In addition, power supply parameters can be set in special utilities. For example, these are found on laptops from Sony, Acer, Lenovo, etc. As a rule, you can open their settings through the assistant in the tray, next to the clock (screen below). If there is nothing like this in the tray - check the Windows control panel.
FILE INDEXING
Description of the problem:
By default, Windows 7 includes file content indexing for faster search (for example, enter some phrase from a text file, and Windows finds it on your disk. Convenient!). But I noticed that only 10% of users use this feature. So if you do not need it, but eats a lot of disk subsystem resources, maybe it should be disabled? ☺
Solution:
To do this, go to "My Computer", select the drive and open its properties.
DISK DEFRAGMENTER
Description of the problem:
Defragmentation is the process of redistributing files on a disk so that they are located in contiguous areas (so that they can be read from the disk faster). If you regularly defragment your hard disk (HDD) - then the speed of reading and writing files will be slightly higher (especially fragmentation is prone to file system FAT 32). You can learn more about defragmentation at.
By the way, if you have an SSD- you can not read what is written below, this type of disk does not need defragmentation.
Solution:
DO I NEED TO TURN OFF THE PC (IS THERE A SLEEP MODE)
Description of the problem:
For some reason, many users do not use sleep mode, hibernation, and other types of putting a computer / laptop into a low power mode. They turn off the computer completely even when they are going to turn it on again in an hour or two ...
Meanwhile, the sleep mode allows you to very quickly restore your work, literally in 1-2 seconds. As a result, you can save a lot of time.
Solution:
It is enough to press the START button, then select "Sleep" from the options for completing the work (as in the screenshot below). If you do not have such an option - most likely a problem with the drivers (I wrote about this above).
Note: In the power settings in the Windows Control Panel, you can configure how long it takes to put the computer into sleep mode (example below).
Here are some modest tips - a few will help make your Windows 7 faster and more responsive (tested more than once on my PCs ☺).
Probably, all users at least once blamed their computer for slow work, while not thinking at all that there are a lot of opportunities to speed it up. Many people believe that improving PC performance is difficult and accessible only to advanced users, but this opinion is not entirely true. Yes, there are methods to improve performance that require a lot of skill in working with a computer, but there are many very simple ways to “overclock” a PC. Every user should be aware of these methods. In this article we will talk about them using the example of the most popular today. Windows versions- you will learn, how to speed up windows 7.
Disable Visual Effects Windows 7
Turning off the visual effects of Windows 7 is the easiest and most affordable option to improve the speed of the system. To perform this procedure, follow the instructions:
3. A new window will open in front of you, in it click on the "Advanced" tab and in the "Performance" section, click the "Options" button.
4. In the "Options" window that appears, in the "Visual Effects" tab, you will see how many visual effects there are in Windows 7. Of course, thanks to them, the platform looks more interesting and pleasant, but they slow down the speed of its work quite a bit.
5. To turn off all visual effects at once, check the “Ensure the best performance” box, and if you want to turn off the effects selectively, uncheck the boxes you want.
6. That's it, for the changes to take effect, you must click "OK" and restart the PC.
Disabling unwanted audio
Along with visual effects, to make it more pleasant for the user to work with a PC, Microsoft also created system sounds. You will be surprised, but they also require certain resources, and disabling them can positively affect the performance of Windows 7.
To disable visual effects:
1. Press the combination Win + R, in the window that appears, write "mmsys.cpl" and click "OK".
2. A new window will open in front of you, select the "Sounds" tab, set sound scheme Silent, click OK.
3. Reboot your PC for the changes to take effect.
Disabling the Search Indexing Option
For users who often search for something in the system, Microsoft has provided a very convenient search indexing option, which makes it easier and faster to find files. However, if you rarely use the system search, this option is completely useless and only “steals” the performance of Windows 7. To disable it, do the following:
2. Expand the "Services and Applications" list, click on the "Services" line and in the list on the right, find Windows Service search.
By default, you can also disable the following services [screenshot below], as practice shows, they rarely benefit the average home PC user.
Removing "extra" programs from startup
Windows has an autoload option. It is responsible for launching a number of programs at the same time as the system boots. These programs include, as a rule, various services and applications, without which the correct operation of the PC will be impossible. But, unfortunately, quite often completely unnecessary third-party programs are added to these programs.
The thing is that third-party software developers include an autoload function in their products, thus making their program more “intrusive”. However, when it comes to running along with an antivirus system, this makes sense. However, there are many programs that run with Windows when they don't need to. Of course, this affects the speed of the PC.
To remove a program from startup, you must:
1. Press the key combination Win + R, in the window that appears, write "msconfig" and click "OK".
2. A window will open, select the "Startup" section in it.
3. Remove the checkmarks from the windows of those programs that you do not need to autoload.
Remember! Without some startup programs, the system will not be able to function correctly, so uncheck only those programs that you are sure are unnecessary.
4. Click OK and restart your PC.
HDD Optimization
At the beginning of the article, we mentioned that we will talk about simple ways to improve the performance of Windows 7, and, for sure, after reading this heading, you thought that we had already gone into the wilds, but this is not the case. We will talk about the simplest hard drive optimization and try to explain in an accessible way why it is required.
The fact is that all files that are written to HDD, break into fragments according to a certain law. This is required in order to maximize the rational use of PC resources. However, it turns out that when a user accesses a particular file, the system has to collect its "pieces" throughout the hard disk. If a lot of unnecessary files have accumulated on your disk, this, of course, significantly slows down the process. That's why, hard disk optimization is a necessary procedure when it comes to how to speed up Windows 7.
The first and most logical way to optimize is to remove junk files and programs. Each user has a lot of “garbage” stored on their PC and it is important to get rid of it regularly. Of course, any, even the most "zero" user knows how to delete files, but sometimes there are problems with programs, although this task is not difficult. To uninstall a program from a PC:
4. You will see a list of the programs you use, decide which ones you no longer need and delete them - to delete, click once on the "undesirable" program and click the "Delete" button.
5. After removing all unnecessary programs, restart your PC.
Another procedure necessary for optimizing a hard drive is its defragmentation. It's a complicated word, but it's simple:
1. Go to "Computer", click on the disk right click mouse, select "Properties" from the drop-down menu.
2. In the window that appears, select the "Service" tab, then click the "Defragment" button.
3. After defragmenting, restart your PC.
If your system is divided into several disks, defragment each of them. Important! The defragmentation procedure, as well as the procedure for deleting unnecessary files, must be carried out regularly.
Meal Plan Optimization
This method Windows acceleration 7 is relevant for laptop users. Very often, disconnecting from the network, laptops automatically switch to a reduced power consumption mode, which, of course, corresponds to the minimum performance. Therefore, it is very important when returning to the network, to switch to high performance mode. No one, of course, forbids the use of this mode and when battery life, however, keep in mind that the laptop in this case will be discharged faster.
To switch to high performance mode:
3. Select the "Power Options" section.
4. Put a dot in the "High performance" box.
Changing boot options
By default, at startup, the system does not use all its resources, this is necessary so that the "cold" iron is not loaded to the maximum. However, if your PC has more than 2 GB of RAM and more than one core, you can change the boot settings, thereby greatly speeding it up. For this:
1. Press the key combination Win + R, in the window that appears, write "msconfig" and click "OK".
2. Select the "Download" tab, check the box "Without GUI".
3. Next, click the " Extra options”, in the boxes “Number of processors” and “Maximum memory”, check the boxes, set the maximum value and click “OK” first in the window “Advanced boot options”, then in the window “System Configuration”.
Results
It has long been no secret that performance in Windows 7 is sacrificed for beautiful animation. In your article Speeding up Windows 7, as I understand it, there was an attempt to solve the problem from the technical side, that is, by changing system settings operating system. It seems to me that you need to optimize Windows 7 first of all by disabling visual effects, and only then experiment with the paging file, the registry, and so on. Sergey.
Windows 7 optimization
Optimization is the process of modifying a system to improve its efficiency. Wikipedia.
No doubt the Aero interface imposes on Windows performance 7 large load and disabling some settings that directly affect the animation, usually immediately affects a significant increase in speed in Windows 7. And of course Windows 7 optimization you need to start by turning off some visual effects. But what? Personally, at my work in Performance Options-> Visual Effects, there is a check mark in the item Provide the most best performance why do I need a workplace beautiful animation and smooth disappearance. Now, if you could smoothly disappear from work and so that no one would notice it, but unfortunately there is no such setting in Windows 7. But my friends at home turned off the Aero interface in Windows 7, the children did not allow me: "It's beautiful, Dad."
Well, we talked a little, let's get down to business. What I propose, personally, I have long found a golden mean for myself in the settings of visual effects, which our readers have asked me about more than once, and here I am sharing my experience.
I'm sure by the time you've read this article to the end, you'll turn off one-third of the visuals and be surprised, "Wow, I didn't even know this was all managed here."
Start->Control Panel->System and Security->System->Advanced System Settings->Performance->Settings. Any visual effect can be disabled by unchecking it and clicking Apply.
1)Animation in the start menu and panel whether tasks. This setting is responsible for the smooth appearance and fading of lists in the Start menu, as well as drop-down buttons on the Taskbar, for example, right-click on the Start menu and hover over the All Programs menu, then we can notice the effect of a smooth drop-down list of programs. Let's uncheck the item "Animation in the Start menu and taskbar" and do the same, as you can see in the illustration, the list of programs now does not drop out smoothly, but quickly, it's up to you to tick it back or not.
2)Animating windows when minimizing and maximizing. The name speaks for itself. When opened, the window appears smoothly, and when closed, it sort of collapses. Let's open, for example, the Computer system folder window in the Control Panel, the effect is clearly noticeable, and now turn it off this setting and open again, no doubt the difference in the speed of the appearance of the window will be noticeable.
3)Animated controls and elements inside a window. Responsible for the smooth highlighting effect on buttons and scroll arrows in dialog boxes. For example, reopen system folder The computer and move the mouse over the scroll arrow, we noticed the highlighting effect, now turn off this setting and do the same. It seems to me that this can be abandoned.
4) Enable desktop composition. Responsible for the transparency effect of each open window in Windows 7, as well as the Taskbar. Windows 7 has to store information about open windows in memory and show us their silhouette when you hover your mouse over a button in the lower right corner of the desktop called Minimize All Windows. Many people think that Windows 7 optimization, you need to start by disabling this effect and the performance gain will not go unnoticed.
5) Enable Aero Peek. In the lower right corner of the desktop, there is a button Minimize all windows, when you hover over it with the mouse, we will observe this effect.
6) Enable eff transparency project. If you disable this effect, then the Windows 7 interface will lose a lot, the transparency effect will disappear in the windows, experiment, maybe your video card will pass this test, it's worth it.
7) Smooth scrolling of lists. You can safely uncheck the box, the effect is not particularly noticeable.
8) Fading menu after calling a command. Turn it off, as the difference is quite difficult to notice.
9) Using display stylesniya for buttons and windows. When this option is disabled, no one will distinguish the design of your operating system from Windows XP - with all disabled visual effects. If you, like me, can not forget XP, you can also choose a classic theme. Right-click on the desktop, select Personalization, then Basic Simplified Classic.
10) Drop shadows on desktop icons. Personally, I don't see much difference whether there is a shadow behind the icons or not, you can disable
11) Display window contents while dragging, it seems to me better to display, it won’t take much resources from you, as you can see in the second illustration, if you don’t display it, it won’t be very convenient.
12) Display shadows cast by windows. The screenshot shows a shadow with an arrow, if it does not suit you, turn off the setting.
13) Show thumbnails instead of icons. This visual effect consumes quite a lot of Windows 7 resources, and when it is disabled, folders will open noticeably faster. It displays all image files in Windows Explorer 7 in miniature, as well as video files and others. If you often deal with images, then using this effect is quite convenient, you can immediately notice the photo and picture you need, but many people working with video complained to me that Windows 7 generates all thumbnails of video files in Windows Explorer. in different ways and sometimes a video file is simply impossible to find in a folder with other types of files, so it takes bizarre forms. By the way, everything can be seen in our illustrations. Black rectangles in the folder, these are our films with you, next to graphic images, but this is how they look when the effect is disabled.
14) Display pr transparent selection rectangle. When selecting several files with the mouse, you can notice a rectangular area moving after it, which does not particularly affect performance.
15) Show shadow under mouse pointer. It practically does not consume computer resources.
16) Smooth jagged screen fonts. The text on the screen, with this visual effect turned off, does not look very nice, let's leave it.
17) Sliding when expanding lists. The effect of smooth drop-down lists, not very noticeable, can be turned off.
18) Save Taskbar Thumbnail View. Feel free to experiment if you need to.
19) when accessing the menu. It consumes a lot of resources and our time too, it is better to turn it off.
20)Fade or slide effects when hints appear. Which is better for you, a hint with an effect or just a quick hint? Disable.
The question is how to speed up the computer great amount users, and interest in it does not fade away. You can really affect the speed of your computer by optimizing the operating system. Most of the functions and capabilities of modern operating systems remain unclaimed by ordinary users. Many after reinstalling the OS do not make any changes to the configuration and are content default settings, which are not the most optimal.
We will analyze in detail all the most relevant methods of optimizing windows 7 to improve computer performance. If you follow our recommendations, you will surely notice that the computer began to work much faster.
Setting up visual effects
Problem. Operating Systems windows families have not only a convenient, but also a beautiful interface. This, in turn, imposes quite serious requirements on the hardware of the computer. With all the abundance of interesting visual effects, hardware should ensure smooth operation and the highest possible performance. If the computer is not the most powerful, then a drop in performance is guaranteed. This problem is especially relevant for owners of low-power laptops and netbooks, whose manufacturers primarily set themselves the goal of increasing energy efficiency and reducing costs.
Solution. To solve this problem, it is recommended to turn off almost all visual effects and leave only the basic ones. In this case, the performance gain is guaranteed to you. Optimizing windows 7 in terms of visual effects is quite simple. Go to the Start menu and type "Visual Effects" in the search bar. Click on the appeared section “Tuning the presentation and performance of the system”.
For convenient settings, put the selector in front of the “Ensure the best performance” item, and absolutely all the checkboxes are removed. Then check the following boxes:
- Enable desktop composition
- Using window and button display styles
- Show thumbnails instead of icons
- Smooth jagged screen fonts
Click "Apply" and restart your computer.
Optimizing the hard drive in windows 7
Problem. All files written to the hard disk are divided into fragments using a special algorithm. This is done to maximize the rational use of the remaining disk space. As a result, when the computer tries to read a file, it collects a huge number of individual fragments scattered throughout the hard drive. This process is aggravated by the presence of tens of thousands of fragments of unnecessary files. This, in turn, can lead to a decrease in the performance of the hard drive and the system as a whole.
Solution. The only effective way out of the problem is regular cleaning of junk files and defragmenting the hard drive. First, audit unnecessary information on your computer. Delete boring movies (which, by the way, take up a fairly large amount of memory), music and other files that have already lost relevance for you. Then uninstall programs you don't use. To do this, go to the "Start" menu --> "Control Panel" --> "Uninstall a Program". We audit outdated applications and get rid of them using the “Delete” button.
After cleaning from garbage, we proceed to defragmentation. To do this, go to "My Computer", right-click on the desired disk and select "Properties" --> "Tools" --> "Defragment". Select the drive and click the "Defragment Disk" button.
Optimizing your hard drive will really help you speed up your computer. The effect will be especially noticeable on those computers where this procedure has not been carried out for a long time. Recall that it is desirable to carry out defragmentation regularly to maintain optimal operation of the hard drive.
Autorun optimization in windows 7
Problem. Even on powerful and expensive computers, over time, a decrease in the speed of loading the operating system is noticed. And in most cases, the culprit is a huge number of programs that run simultaneously with the operating system. Update managers are added to startup various applications, agents social networks, all kinds of messengers, antivirus. By the way, it’s better not to remove the latter from autoload, because ideally antivirus program must constantly protect the computer in real time. We will disable all other “unexpected guests” from autoload.
Solution. For simple and effective removal extra programs it is recommended to use CCleaner from startup. Her main specialty is cleaning the registry (we'll talk about this later), but she also does an excellent job with autoload optimization, providing the user with a convenient and intuitive clear interface.
Run the program, go to the "Tools" --> "Startup" tab and use the "Turn off" button to remove all programs that you do not need from automatic launch.
Diagnosis of RAM and registry
Problem. It is believed that a littered registry can negatively affect the speed of a computer, as well as problematic RAM. With the registry, everything is clear. If installed applications are not completely removed, “garbage” remains in it (application settings, links to non-existent shortcuts, incorrect file extensions). As time goes by, there is more and more trash. And if we want to speed up the computer, then the garbage must be removed.
With RAM, everything is somewhat more complicated. This is a very important component of the computer and talking about optimal performance systems without adequate operation of RAM simply do not have to. The reason for the appearance of failures in the RAM can be a manufacturing defect, a malfunction in the power supply, and even voltage drops. In any case, optimizing windows 7 without fail means diagnosing RAM.
Solution. You can clean the registry using the previously mentioned CCleaner program. RAM diagnostics can be carried out using the operating system. To do this, open the “Start” menu and in the search box, type “Diagnostics of computer RAM problems”.
A window should appear in which you need to select the type of check (it is recommended to choose the first option).
After restarting the computer, the memory test will begin. It can take a long time, so do not schedule any urgent computer-related tasks during the diagnostic period. When checking on the screen, you will see something like the following window:
The end of the diagnostics will be accompanied by a restart of the computer. The next time you log in, you will be able to see the results of the check. Windows 7 optimization must necessarily include work with the registry and RAM.
Windows 7 optimization for multi-core processors
Problem. Many users have computers equipped with multi-core processors (with 2 or more cores). More cores in the processor should have a positive effect on the speed of the computer. Although the operating system itself automatically checks the type and characteristics of the installed processor, quite often only one core is used when the computer starts. Naturally, in this case, the boot speed of the operating system is reduced.
Solution. The solution to this problem is very simple. The user can force the system to boot using the power of all processor cores. To do this, go to "Start" --> "All Programs" --> "Accessories" --> "Run". Enter the command "msconfig" and click "OK".
In the system configuration window that appears, go to the “Download” tab --> “Advanced options…”. Check the box next to the “Number of processors” item and select the maximum number. Click "OK".
If you do not know how to speed up your computer, or rather how to influence the speed of starting the operating system, then this method It suits you perfectly.
Removing unnecessary gadgets
Problem. The standard and optional gadgets used in windows 7 are undoubtedly very convenient and useful. Many users are happy to use them in their daily work to facilitate access to interesting information. On the other hand, gadgets can directly affect the speed of a computer, naturally in a negative way. Such gadgets will consume the resources of your system. On a powerful modern machine, this may not be noticeable, but on a more weak computers performance drop will be noticeable.
Solution. Windows 7 optimization in terms of gadgets does not include them complete removal. Leave 1-2 of the most frequently used and useful gadgets, and delete the rest. All the same, with a high degree of probability it can be argued that you will receive most of the interesting information on the Internet. Why then once again load your system.
Optimizing windows 7 with ReadyBoost
Problem. Windows 7 operating system can use high speed devices flash memory for efficient data caching of the most frequently run applications. In fact, the memory of a USB flash drive or SD card can be used instead of a swap file. Such a cunning manipulation makes it possible to speed up the read-write procedure, which in the end will positively affect the speed of the computer and the overall performance of the system.
Not all windows users 7 can increase the amount of RAM in a standard way(buying a new bar). A variety of reasons can prevent this. These are the restrictions imposed by the chipset manufacturer or motherboard on their products, and the inability to purchase RAM of a suitable format.
Solution. To expand the computer's RAM, you can use standard USB flash drives and SDHC/SD/MS flash cards. To use a flash card, you will need a special card reader that is compatible with the format of the card. ReadyBoost technology is natively built into the operating system, so you don't have to download and install additional software.
Minimum Requirements for drives when using them in ReadyBoost:
- Support USB standard 2.0/3.0
- Minimum read speed of 2.5 MB/s for information in 4 KB blocks
- Minimum write speed of 1.75 MB/s for information in 512 KB blocks
- Minimum free space 64 MB
Before choosing a drive for ReadyBoost, be sure to check its speed specifications and make sure they meet the requirements. Using high-speed flash cards will provide the maximum performance boost.
We go to "My Computer", right-click on the external drive and click "Properties". Go to the "ReadyBoost" tab. We set the selector opposite the item “Use this device” and use the slider to set the limit for the amount of memory used. Then click "Apply" and "OK". If you want to give the system access to all free memory of the external media, then set the selector opposite the item “Give this device for ReadyBoost technology”.
Use this tricky one. We hope it will help you answer the question of how to speed up your computer.
Power optimization in windows 7
Problem. Very often, when working on a computer, users forget to configure the power management scheme - a set of hardware and system settings that are responsible for power consumption individual components systems. The power plan can be set to maximize energy savings (respectively, minimum performance), to balance power consumption, or to increase computer performance (maximum power consumption). You can simply forget about this simple parameter and at the same time adversely affect the performance of the system.
This problem is relevant for laptop owners. By default, the system sets the balanced power mode. When the laptop's battery runs out, it automatically enters the power saving mode. Later, when the laptop is connected to the network, few people remember about the economy mode and the need to switch it. So on simple things, the speed of the computer is lost.
If you are using a personal computer or laptop (but running on AC power), adjusting your power plan can speed up your computer and improve overall system performance.
Solution. The solution to the problem is to control the power supply mode. Go to "Start" --> "Control Panel" --> "Power Options" and select the "High Performance" mode.
If desired, you can set up a power plan. To do this, select "Setting up a power plan" --> "Change advanced power settings". We set our values as desired.
conclusions
We have analyzed 8 ways to optimize windows 7 that will help increase the speed of your computer. It is very difficult to fit all optimization methods into one article, so this is only the first part of the material. In future articles, we will continue to analyze interesting and effective ways optimization, since this topic is quite extensive and interesting.

Windows 7 optimization or how to improve computer performance
It is possible to increase computer performance by optimizing windows work 7. Many existing functions in windows that affect the speed and performance of a PC are not used by ordinary users. Most use the default settings, and they are not the best for PC performance. Below are the main ways to increase speed to improve the performance of your windows 7 computer.
Visual Effects Optimization
A task
windows 7 has a lot of beautiful visual effects, which increases the load on components and reduces PC performance. This reduces the performance of the computer, especially in the case of not the most modern hardware.
Answer
It is necessary to turn off the visual effects, leaving only the standard ones. This will immediately increase the speed and performance of your computer. In windows 7, you need to type "Visual Effects" in the search box through the "Start" window.
Next, click on “Tune system presentation and performance”. In order to speed up the process, you must activate the "Ensure the best performance" option.
- Increase the clarity of the display of fonts;
- Application of display types of windows and buttons;
- Enable desktop composition;
- Show thumbnails instead of labels.
Then click OK and reboot.
Check and debug the work of the hard drive in windows 7
A task
Data on the hard drive is entered in parts for optimization disk space. As a result, a PC, when opening files, spends a significant amount of time searching for them, and if there are a large number of junk files, the process slows down even more.
Answer
It is necessary to periodically check for and remove unnecessary files, defragment the disk. At the first stage, you need to manually delete unnecessary data from the computer's memory, for example, unused programs, old movies, music, etc. In order to remove applications, you must enter through the "Start" in the "Control Panel" and then in the "Uninstall a program".
Next, you need to perform defragmentation. You need to enter "My Computer", in the context menu of the disk, select sequentially: "Properties" - "Tools" - "Perform defragmentation". Click on "Disk Defragmenter". 
Cleaning the "Startup" directory
A task
You can often increase your computer's boot speed by simply getting rid of unnecessary startup programs, such as social media messaging services, various software updates, antivirus, and so on. In fact, everything except the antivirus can be removed.
Answer
It is recommended to use the CCleaner application. It will help clean the registry and optimize startup speed. In the application, you need to enter the "Service" tab, and then to "Startup". By clicking on "Turn off", go through all the applications that you do not constantly use. 
Cleaning the registry and RAM
A task
When you uninstall programs, “garbage” accumulates on your computer (program settings, links, unnecessary shortcuts, erroneous extensions). The optimal operation of RAM is affected by a possible marriage during its manufacture, incorrect operation of the power supply and changes in mains voltage.
Solution
Cleaning the registry is very easy to do with the CCleaner application. Analysis of the work of RAM is performed using the built-in windows functions 7. In order to perform an analysis of the RAM, it is required through the "Start" to use the search bar, where to type "Diagnosis of computer RAM problems."
After that, a menu will be displayed where you need to click on the 1st diagnostic method.
The PC will reboot and start analyzing the RAM. The process takes a significant amount of time. Having finished the process, the PC will restart again and the user will have access to information about the analysis performed. 
Connecting all processor cores
A task
To effectively increase the performance of your computer, you need to optimize Windows for multi-core processors.
Answer
It is required to tell the OS to boot using the resources of all cores. Through "Start" - "All Programs" - "Accessories" - "Run" you need to type "msconfig" and click on "OK".
In the menu that appears, enter "Download" - "Advanced options ...". Check the "Number of processors" checkbox (to improve the performance and speed of the PC, it is recommended to check the maximum possible number). Click on "OK". 
Disable unused gadgets
Gadgets slow down PC performance. For maximum effect it is recommended to disable them all.
Conclusion
The article discusses only the main methods for increasing the speed and performance of a computer.
This topic is very extensive and it is impossible to cover it entirely in one publication, so additional methods for optimizing windows 7 are described in a separate section.

Optimizing and improving the performance of windows 7 (64-bit)
Windows 7 is a complex set of interactions between many programs, so a huge number of factors affect the speed of the OS. You can’t just disable a couple of programs or change one setting to get a significant increase in system performance.
System optimization is not an easy task that requires care and an integrated approach. This article covers the main possible actions to increase the performance of 64-bit windows 7.
Using an SSD
If as system disk use not an ordinary hard drive (hard drive), but a solid state drive, then this event alone will quickly and significantly increase the performance of a PC on windows 7 (64 bit). The main advantage of an SSD drive is that it is many times faster than the data storage and playback speed (500 Mb / s) compared to hard drives.
Even booting the operating system from this media takes only a few seconds. Currently, all the equipment used in computers is high-speed, the only weak link in the chain of interaction is hard drives HDD, which slow down the entire system.
Install a new BIOS and check if the software is up to date
It is necessary to perform the following analysis: are the drivers updated, does the PC have a fresh BIOS? When installing drivers, you should take into account the bit depth, i.e. for 64-bit OS, you need to download advising software for computer hardware. In the absence of drivers for specific device for windows 7 (64), you can download the appropriate software for Vista.
Upgrade RAM
Often the problem of a slow PC with windows 7 is a banal lack of RAM. best method fixing the problem is to increase the RAM. This event always significantly increases the speed of the PC and leads to the optimization of the OS. In order to ensure comfortable operation of windows 7 (64-bit), you need at least 4 Gb of RAM. 
Optimize interface
windows Aero in the "Seven" is the main "devourer" of system resources. Although it only adds some beauty and personality external design and is completely unnecessary to work. A significant decrease in performance due to Aero occurs on a PC with an insufficiently powerful video card or if it is built into the motherboard.
Turning off all Aero features that are almost invisible to the eye will increase performance. To do this, you need to open the "Control Panel", then go to the "System" tab and to the "Advanced system settings". Next, in the "Advanced" tab, find and click on "Settings".
Here you can turn off such functions as: showing the contents of windows while moving, sliding effects, fading menus, animations, casting shadows by icons, cursor and windows, etc. Even disabling only some effects will already increase the speed of windows 7, and in the case of an unpretentious user, it is recommended to click on "Ensure the best performance" in the settings.
Optimize the list of applications in autorun
A significant number of applications are loaded simultaneously with windows 7. The developers of these programs ensure that they are loaded in the background and the computer owner does not see them. But this is only necessary for utilities that are used constantly.
It is necessary to disable auto-start of unnecessary applications. The following programs must be loaded with the operating system: hardware drivers, firewall and anti-virus utility. To optimize the list of automatically loading applications, you need to hold down the "WIN" key and press "R" and enter "msconfig". Next, open the "Startup" tab.
Startup programs can be seen in the system tray area on the taskbar. However, not everything is displayed there. Developed specifically for windows application"AutoRuns", which is distributed freely from the Microsoft resource. "AutoRuns" shows the full list of downloadable applications. In the window this application you just need to uncheck the boxes next to unnecessary program. 
Disable unnecessary services
By disabling the startup of some services, you can improve the performance of your computer. To do this, you need to enter the "Control Panel", then to "Administration", where in the "Services" tab select the unnecessary service and click "Disabled". 
Periodically defragment disks
With increased data fragmentation, the hard drive is forced to do extra work, and this affects the performance of the PC. It is recommended to run defragmentation manually to organize files in order to optimize the functioning of the hard drive. 
Turn off automatic defragmentation
The creators of windows 7 have provided background defragmentation, during which the performance of the computer is significantly reduced. It is necessary to configure the process through the "Start" button. Select the "Standard" line in the "All Programs" tab, then enter the "Utilities", where to find "Defragmentation". To increase the speed of windows 7, a prerequisite is the regular manual defragmentation.
Get rid of old, unnecessary or obsolete applications
Some PC manufacturers are releasing their devices with installed apps not needed by the user. They slow down the performance of windows 7, as they use memory and disk space.
It is advisable to rid the computer of all unused applications. This list should be supplemented with programs that the user himself installed, but over time have lost their relevance. A simple act of removing these programs will improve system performance.
Remove unused gadgets
In windows 7, gadgets increase the comfort of using a PC, but they all need system resources to start and function. When using only the necessary regular use gadgets system performance will increase.
Perform a computer restart
This recommendation can easily be followed by any user. Restarting your PC regularly is easy. It is recommended to perform this simple procedure once every 7 days. This cleans up memory and shuts down some failed services, resulting in improved system performance.

How to increase the speed of the windows 7 operating system
The operating system has a rather complex structure. Its work is provided by a huge number of different programs - services and processes. There are many factors that affect speed and performance windows systems 7. This article describes how you can increase the speed of your personal computer.
The physical part of the computer (processor power, amount of RAM, solid state drives) is not considered in the article. Obviously, the better the PC, the more tasks it can solve, and the faster it copes with them. This guide describes the process of fine-tuning the system, which will bear fruit on any hardware.
General information
To begin with, it is necessary to analyze what exactly affects windows performance. The guide covers only those factors that can be influenced by any user without help from computer specialists:
defragmentation
This feature allows you to increase the speed work hard disk and therefore the entire computer. By using special utility the system sorts all the information on the media, optimizing the path of the read head. 
Over time (as a result of deletion, new files, copying and editing), the data becomes fragmented again, and the process must be started again.
Defragmentation is performed as standard windows, and with the help special programs third party developers. Also in the OS, you can set up a schedule for regular operation at a convenient time for you. 
Note! Only the hard drive (HDD) needs regular defragmentation. Solid-state (SDD) from such a procedure only wear out, without receiving any increase in performance.
swap file
The function of the paging file is to compensate for the lack of free RAM on the computer. Part of the contents of RAM is transferred to the hard disk, freeing up space for tasks of paramount importance. If you have a lot of physical memory installed, for example, 16 or 32 gigabytes, these settings do not make sense.
To increase the swap size in windows, you need to do the following:
Performance settings
AT windows settings there is a special section dedicated to increasing computer performance. How to open it is described in the previous section of the manual.
In addition to setting the swap volume, users may be interested in the following options:
autostart
If you want to reduce windows boot time and improve performance, it is recommended to disable unnecessary applications from autorun. For example, if you rarely use Skype, you can cancel its automatic launch at the same time as the system starts, and turn it on only when necessary.
You can manage autorun in the configuration menu of the applications themselves. In torrent trackers, clients for cloud storage, instant messengers and other utilities running in the background, there is a special item in the settings.
But it is much more convenient to work with a single list for windows:
Registry optimization
To avoid any inconsistencies in the registry, you must correctly install and remove all applications. If you still have problems, please use CCleaner to clean the registry of "garbage" and bring performance back to its previous level.
The utility can be downloaded for free from the official website of the developer - Piriform. Go to http://www.piriform.com/ccleaner and click on the green "Download free version" button. Install the application following the instructions of the Wizard. 
AT running program go to the "Registry" section, and click the "Search for problems" button, and then - "Fix".

Increasing the performance of a computer with windows 7 installed
New powerful computer pleases users with its performance, but over time, its speed is steadily declining. In this case, many have a reasonable question, how to speed up windows computer 7, but without spoiling anything in the system.
Considering the question of how to configure windows 7, we have already touched on the problem of using various programs and archives with settings. It was about tweaks - small tricks that help increase system performance. However, you can do without third-party software.
You can really affect the speed of a PC or laptop using the usual system optimization.
Many windows features are not in demand among ordinary users, so they can be safely disabled, increasing the performance of the machine.
Disabling visual effects
Beautiful windows interface 7 is a great advantage and at the same time a serious drawback when it comes to optimizing computer performance.
Various visual effects place high demands on the hardware, slowing down the execution of some more important processes.
If you have a low-power laptop or a computer with old hardware, then performance drops with visual effects enabled cannot be avoided. To fix this shortcoming in windows 7, you can use the built-in tools and remove all unnecessary "chips".
To bring the interface to normal view, you must leave the four effects marked in the screenshot turned on. After that, click the "Apply" button and restart your computer for the new configuration to take effect.
HDD Optimization
Files written to the hard disk are divided into fragments that are scattered over the entire surface of the media. This was done primarily for the rational use of free space, but as a result it often turns out that when the user accesses a specific file, the computer is forced to collect fragments scattered over the entire surface of the disk.
A huge number of fragments of already unnecessary (or deleted) files are also added here. The result is a decrease in the performance of the hard drive and, as a result, the system as a whole. There are two ways to fix this problem:
- Periodic cleaning of the disk from temporary and simply unnecessary files.
- Defragmentation of the hard drive.
Remove from the computer all unnecessary files and programs that take up a lot of space, but are not used for their intended purpose. Leave only the essentials that you can't do without.
To delete temporary files:
After cleaning the system of debris and uninstalling unnecessary programs, you can proceed to disk defragmentation, which is performed standard means windows:
Hard disk optimization is one of the most effective ways increase the speed of the computer. This will be especially noticeable if you have not defragmented for a long time and have not destroyed "computer junk" for a long time.
Increasing the paging file
The lack of RAM and the inability to install an additional bar often leads to the fact that users cannot qualitatively improve the performance of the machine and are forced to put up with a low system speed.
You can increase the paging file using a USB drive and the ReadyBoost technology built into windows.
Can be used as storage regular flash drive or an SDHC/SD/MS memory card. Even a regular smartphone or any other device with built-in memory that meets the following requirements will do:
- Support for USB0/3.0 technology.
- Availability of free space (minimum 64 MB, but usually more than 200 MB is required).
There are still some restrictions on the data transfer rate, but they are quite democratic: any modern drive has much the best performance than needed for ReadyBoost technology to work.
If you want to provide everything free place for the swap file, select "Provide for ReadyBoost Technology".
Startup cleaning
Even on powerful new computers, after some time after the start of continuous operation, the user notices a decrease in the speed of starting the operating system. First of all, this is due to a large number of unnecessary programs in autorun, which are added there without the knowledge of the owner of the machine.
Various messengers, applications for automatic update, social network agents and other similar programs, during installation, must be registered at startup and run along with the system, taking up resources.
Most the best solution- remove all applications from startup, except for those vital for the system. The latter include antivirus with its services and system utilities. You can clean autoload using CCleaner:
If there is no CCleaner utility, then use the standard tools:
In windows 8 and 8.1, this operation can be performed on the "Startup" tab in the "Task Manager".
Checking the registry and RAM
The tails left after the removal of programs in the registry negatively affect the performance of the system, which leads to a decrease in the speed of the computer. The solution is simple - periodically cleaning the registry using the CCleaner utility already mentioned above.
If you have never cleaned the registry, then after the first “cleaning” you may notice a serious acceleration of the system.
Do not forget about the RAM, in which there may also be various failures that affect the final performance. To check the RAM, use the built-in tool "Diagnostics of computer RAM problems".
Choose the first option, which means reboot and check. Don't forget to close all programs. 
The check can be quite long, so do not schedule any tasks related to the computer during it - it is not recommended to interrupt the diagnostics, as this can lead to serious errors.
Power Options
The minimum number of users remembers to adjust the power settings, although this is one of the important components of adjusting computer performance. Typically, the power management scheme has three modes:
- Maximum savings - minimum productivity.
- Balanced energy consumption.
- Maximum energy consumption - maximum performance.
Switching the power mode is especially important for laptop owners. By default, the system is set to balanced mode, but as soon as the battery runs out, power saving mode is automatically activated, which reduces performance.
When you turn on the laptop to the network for charging, the economy mode does not switch, although there is no need for it anymore. On such trifles, users lose moments, which then add up to a noticeable slowdown of the computer.
If you are working on a computer or laptop that is constantly connected to the network, then be sure to configure the power scheme:
- Go to "Control Panel".
- Find the "Power Options" section.
- Select High Performance mode.
If necessary, you can adjust the scheme for yourself by clicking on the link “Setting up a power plan”. On the "Advanced Options" tab, you can set your own values.
Enable all processor cores
It is now almost impossible to find a working computer that has only one core; modern machines have 2 or more cores available.
Usually, the operating system automatically checks the type of processor installed, but it often happens that only one core is used at boot.
You can fix this deficiency on your own:
Now, when starting the operating system, all processor cores will be used, which will significantly speed up loading.
Replacing thermal paste
Another useful advice, allowing you to seriously increase the speed of your computer - replace the thermal paste on the processor.
