Windows 10: DWM.EXE disabled in Windows 11

Hi, Microsoft needs to put a pointer if DWM.EXE is not available in Windows 11.Note: I am still using Windows 10.

I don't know if it is even possible to disable DWM and still have Windows working normally but I found a list of solutions that can solve problems related to DWM:

Get better Game Performance under Vista by disabling DWM on a per-application basis!

I just came across this tip/tweak, which probably many who are familiar with Vista already know... It's about disabling the aero effect on a per-application basis, so that you get vista basic interface during gameplay (when you're not going to see it) and it switches back to aero when you exit the game.

DWM, or the Desktop Window Manager, turns the graphics card into a shared resource which allows for the Aeroglass effects and the tear-free desktop. When running normal applications, this is a good thing because it offloads the graphics work (the bulk of which was handled by the CPU in Windows XP) to the GPU, which, when running normal applications is sitting in your computer doing nothing. With Aeroglass/DWM on, the CPU is freed up for other duties as all of the desktop graphics are now handled by the GPU.

In DirectX 9 and OpenGL games however, having Aeroglass/DWM on can decrease performance. This is for a number of reasons :
1.DWM makes the video card a shared resource. When DWM is on, programs are not allowed direct access to the video card.
2.DWM uses both System RAM and VRAM because it maintains an offscreen buffer for every window.

Fortunately, Microsoft has provided a way to disable DWM on a per-application basis so you can still enjoy Aeroglass when not running games. To disable DWM on a per-application basis, right click on the application/game's icon and select properties. Navigate to the compatibility tab, then find and check Disable Desktop Compositing. Now, whenever you launch that program, Windows Vista will temporarily switch back to the Windows XP style graphics subsystem.

DirectX 10 games shouldn't be affected as much (if at all) by having DWM on because the DirectX 10 API is designed around having the GPU as a shared resource and is better able to handle GPU multitasking.

With a few simple steps, on most setups, you can easily make your games run as fast or faster than in Windows XP under Windows Vista.

This will work on both the 32-bit and 64-bit versions of Windows Vista.

With this note: "The steps below only work for Windows Vista and Windows 7. Desktop Windows Manager is not displayed in the Services window on Windows 8 and Windows 10, and therefore cannot be turned off or disabled."
