Disable compatibility mode in windows 10 operating system

Compatibility mode in the new operating system from Microsoft allows you to work with almost any software that ran on windows XP, 7 or 8, but refuses to work in the new version. However, sometimes it introduces some drawbacks to working with programs. To eliminate the inconvenience, the mode can and should be turned off, which is quite simple to do.

What

Compatibility mode is what allows the operating system to run games or applications that worked well in previous versions, but do not run correctly in the current version of the system. The check occurs automatically at the first start of any process, and the system independently selects the optimal parameters that allow it to work more or less correctly. However, it also takes away the ability to configure the launch manually, which may be inconvenient for some users.

How to turn off

Compatibility mode is not always needed, so disabling automatic launch settings is possible in several variations:

  • Complete service stop.
  • For one application only.
  • Through the Group Policy Editor.

Stopping a service

Completely stopping the compatibility check and setting options once and for all will solve the problems that are caused by this process. If necessary, you can always not only disable, but also enable the Assistant back.

To open all services, you need to launch the Run tool using the Win + R keyboard shortcut and enter the services.msc command.

Among the extensive list that appears after clicking on "OK", you need to find the "Program Compatibility Assistant Service". This line should be selected, and then right-click on it. There are two possible scenarios here:

  • Stop temporarily. This option will disable it only until the computer is restarted, then the Assistant will be enabled again. To do this, just click on "Stop" in the drop-down menu.

  • Completely disable on demand. Until the user turns on the Assistant manually, it will not work. In this case, you need to go to "Properties" in the same menu, and then in the "General" tab in the "Startup type" line, enable the "Disabled" option. After that, save the changes.

Shutdown for one program

Compatibility mode in windows 10 can be stopped for a specific application. Such a selective shutdown can be done with a few simple steps:

  • Right-click on the desired shortcut and click on "Properties".
  • Go to the section called "Compatibility" and uncheck the box where the frame in the screenshot is.
  • Click OK and exit Properties.

Through Group Policy

To disable using group policy, you must enter the gpedit.msc command in the Run tool we already know (Win + R). After clicking on "OK", a new window will open in front of the user called "Local Group Policy Editor". Here you need to find the "Administrative Templates" section, where to open "Windows Components". Then you need to click on the names in the sequence (highlighted in the screenshot):

  • Application compatibility.
  • Disabling Assistant.
  • Disabled.

How to disable compatibility mode in windows 10 in different ways

The new tenth version of the windows operating system includes a feature to check the compatibility of outdated programs. Before the user launches an application that is designed for older operating systems of the windows family, a dozen automatically starts the compatibility check service.

This service checks the application for compatibility and sets the optimal parameters for it. According to Microsoft, this way of launching helps beginners to use old applications without any problems. For more advanced users, this method is not entirely suitable, since it does not have the ability to manually configure program compatibility.

In this article, we will look at disabling compatibility mode for legacy software, and also show how to run programs in this mode manually. It is also worth noting that turning off this mode is associated with disabling the service on windows 10.

Disabling the service may cause the Program Compatibility Assistant to become unstable, causing some applications to function incorrectly. Therefore, this material is intended for experienced users.

Manually disable the Program Compatibility Service

To disable compatibility mode, we need to get into the Services snap-in. To do this, you need to open the Control Panel in windows 10 using the Run application and the Control command, as shown below.

And the Run utility itself is launched when you press Win + R.

You can launch the "Control Panel" in another way. To do this, right-click on the Start menu in the lower left corner of the screen and select the desired item there.

After these steps, the "Control Panel" will be launched. In the panel, go to the "Administration" component. To do this, follow the links in the following order: "System and Security", "Administration".

In the "Administration" component, launch the "Services" shortcut, after which the snap-in we need will start.

Now we need to find the "Program Compatibility Assistant Service".

The list is not small, scroll down.

After starting it, the service settings window will open. To stop this service, click the Stop button. These steps will disable automatic support for older software. To re-enable it, follow the same steps and click the Start button.

Disable the Program Compatibility Service using the command line

You can go to the windows 10 command line using the search by typing cmd in it. It is also worth noting that the command line should be run as Administrator.

After starting the command line, you can start managing the service. You can stop the service with the net stop pcaSvc command

You can start this service with the net start pcaSvc command

As you can see, this method is more automated. It will allow you to very quickly disable and enable legacy software compatibility mode. And also solve the problem on a large number of PCs in a short time.

Running an old app in compatibility mode manually

For example, we will set the support settings for the old operating system in the 1998 game Need for Speed ​​III: Hot Pursuit. To do this, we install the game on the computer and go to the properties of the shortcut that links to the game's executable file.

At this stage, setting up the game for the old OS is completed. Now you can safely run Need for Speed ​​III: Hot Pursuit and enjoy the great races of the time. Thus, in addition to old games, you will also be able to run old utilities that only work on old OSes.

Outcome

As you can see from the material described above, disabling compatibility mode in windows 10 is very simple and can be done quickly. Therefore, we hope that our article will help experienced users and novice system administrators.
