What Is Desktop Composition?
So what is desktop composition, and what it means to have it enabled? Having the desktop composition enabled means that individual windows will not draw to the primary display directly as it was used to happen in earlier Windows.
The drawing of the screen is actually redirected to the off-screen surfaces in video memory. This drawing is then rendered as a desktop image and presented for us on the display.
The Desktop Window Manager (DWM) is the service behind the Desktop composition. This DWM service then enables the visual effects and the features like the Aero theme on the desktop using the Desktop composition.

How To Disable Desktop Composition In Windows 10?
The most asked questions online about Desktop composition is if it can be disabled in Windows 10. Well, there is no setting that you can use to disable Desktop Composition in Windows 10. Neither one can disable the DWM from the methods that work in Windows 7 and Vista.
From Windows 8, Microsoft has removed the ability to disable desktop composition. However, there is a way you can force close it, although we don’t recommend you trying it as many mishaps can occur trying to disable a Windows service that isn’t supposed to be disabled in Windows 10.
Steps To Disable Desktop Composition
To disable Desktop Composition in Windows 10, follow the steps given below:
- Press the Ctrl + Shift + Esc keys to open the Task Manager on your screen.
- In the Performance tab, select click on the Open Resource Monitor option.
Resource Monitor will now open on your screen.
- In the CPU section, locate the winlogon.exe and right-click on it.
- Select the Suspend process option and immediately click on the Monitoring tab and then select the Stop monitoring option. If you don’t do it quickly, then winlogon.exe can disappear and you will have to restart to get it back.
- Now, open the Task Manager again and locate the Windows Explorer in the Processes tab.
- Right-click on it and click on the End task option.
- Similarly, End task Application Frame Host, Search, Shell Experience Host, and all the other modern apps or UWP.
Note: If you don’t end the modern apps, then you will have a black screen once you end DWM later. So, you will have to blindly resume winlogon.exe, which is not an option, or restart your computer.
- Now, locate the Desktop Window Manager (DWM) in the Processes tab and also End task it.
- Next, select the File option in Task Manager and click on the Run new task option.
