Hello. On this page I will tell you how to clean the registry manually. This will help you not only when the program is not installed, it will be useful in order to keep the registry clean. That is, you will learn how to delete unnecessary entries in the registry. Begin.
How to clean the registry?
In order to clean the registry, you can use third-party programs. There are a lot of similar programs, for example, "CCleaner", " Reg Organizer» and the like. I talked about these programs in these notes: and.
These programs are good, but they do not always completely clean the registry. And in order to better clean the registry, we will use the manual method.
Cleaning the registry manually
While on the desktop, press the key combination "Windows + R". The Run utility will open. In the window of this utility, enter the following inscription "regedit" and click "OK". The Registry Editor will open. This is where we will work.
While in the registry editor, press "Ctrl + F", a search window will open. In this window, enter the name of the program whose entries you want to delete. Please note that you must enter the exact name of the program. But, be careful! There are programs with similar names, for example, you have installed the program " Microsoft office", and the program "OpenOffice" is also installed.
If you enter just the word “Office” in the search, you can spoil the performance of the wrong program, the entries of which you want to delete. Therefore, in such a case, I would enter the exact name of the program, for example, "OpenOffice", then you will not affect the records of the "Microsoft Office" program.
Also, I do not advise you to specify too long names in the search, for example, "Apache OpenOffice", because not all registry entries will contain the word "Apache". In the worst case, the search will not find records on similar request. I hope everything is clear here.
We figured out how to enter the name of the program whose entries we want to delete. Enter a name and click "Find Next".
Now the registry editor will look for files that contain the word that you specified in the search. As soon as it finds a similar file, the search will stop and you will see a highlighted file that you need to delete.
Just click the "Delete" button and confirm the deletion. To continue the search, press the "F3" button. Next, the following file will appear, which you will also delete. Do the same until the registry editor writes that the search is completed "Registry search completed." You can, just in case, check everything remotely by pressing “Ctrl + F” and “Find Next”, if a message also appears that the search is completed, then you can close the registry editor, you have completed your task.
Now about possible "extraordinary" situations. It happens that during the deletion they will write to you that you cannot delete given file. What to do in this case? In such a case, you need to uninstall in "Safe Mode". That is, you need to restart your computer and enter safe mode in the way that you know. For example, if you have a Windows 7 operating system, after rebooting, as soon as the first picture appears, press and hold the "F8" button, select "Safe Mode" in the menu that appears.
AT safe mode do the same as you did before. Open the registry editor and delete files with entries. That's all. As you can see, everything is very simple! But, if everything is not completely clear to you, watch the video below, in the video I showed manually cleaning the registry using the example of a remote program.
Try it, you will succeed. I wish you success!
Video: Cleaning the registry manually.
The Windows Registry is a hierarchical operating system database that contains settings and other information concerning work the system itself, user profiles, third-party software, and computer hardware. This information is directly contained in registry keys – string parameters with certain values. The keys are cataloged into their subfolders, which in turn are part of the parent folders, subfolders, and sections.
Cluttering an important Windows work area
The more data is contained in the registry, the wider the scope of the search, respectively. And the more time the operating system needs to access to the required data. This negatively affects performance. Database Growth system registry promotes work dynamics with a computer in terms of experiments with third-party software. When installing programs, they register their keys in the registry, which are stored there even after these programs are removed from the system. Invalid remote software keys over time accumulate and litter such an important working area of Windows.
The way out of the situation is periodic cleaning. But it is important to understand that this kind of optimizing operation will not solve the problem globally. low power computers, in particular with slow HDDs on board.
Cleaning can be done by manual removal each of the unnecessary keys, or in staff editor Windows Regedit.exe, or using special third party programs. The latter usually provide for the possibility automatic search non-working keys - an option suitable for most users.

defragmentation
Defragmentation is a separate system-optimizing feature that can be part of disk cleaners or disk defragmenters. What is its essence? When it comes to defragmenting the registry, we mean merging fragments its files - the Default, Software, System files located on the C drive in the "Windows" directory. it not optimization data structures within it, as many believe. And therefore, such an operation simply does not make sense. First, Windows is constantly draws to the registry data, and its files on the disk will, accordingly, also be permanently fragment. Secondly, the HDD defragmentation process is included in the automatic maintenance operations of Windows 7, 8.1 and 10.
Important: it is impossible to allow defragmentation of even the disk as a whole, even its individual files in relation to SSD- drives. And Windows is well aware of this. These devices have a different storage mechanism than the HDD: their read speed does not depend from a continuous sequence of data clusters. On the contrary, overwriting data during the defragmentation process will reduce the life of the SSD.
How to remove a program from the registry
To remove an individually selected program from the registry, i.e. destroy all her keys run staff editor regedit.exe.

operating room registry Windows systems is a large database that stores all information about the PC configuration, OS settings, information about installed programs and their paths. Over time, this database is filled with obsolete and incorrect entries (keys), which appear in Russian due to the crooked hands of the creators of the programs and the operating system itself. For example, you decide to delete an already boring game. We launched the uninstaller, waited for the end of the process, and, it seems, that's all, but there could be entries about this game in the registry, which are now dead weight there. And the longer you use your computer, the more garbage accumulates in the registry. This slows down the overall performance of the computer. and slows down the launch of programs, so you need to periodically clean the registry.
