During Windows 10 installation, the computer gradually became unresponsive. How do we fix this problem at the moment? You can see that the Desktop Window Manager occupies a lot of memory in the Task Manager. The Desktop Window Manager allows users to control the functions of Win 10, such as visual effects, 3D Windows transition animation, etc. The Desktop Window Manager operates in the background, and the CPU or memory usage is low. However, dwm.exe must use some hardware acceleration in order to make the animation smoother. The following methods can be used to fix the problem when the Desktop Window Manager memory is too high!

Windows Desktop Manager: What is it?

The Desktop Window Manager (dwm.exe) is a synthetic window manager which can be used to render all those nice features in Windows: transparent windows, real-time taskbar thumbnails, Flip3D, and high-resolution monitor support.

The application stores the picture in memory rather than displaying the picture directly on the screen. Before sending the composite view to your screen, Windows will create a “composite” view of all the windows on the screen. When Windows displays windows hierarchically, it adds effects such as transparency and window animation because it composes and displays the contents of each window.

Is It Possible to End Desktop Window Manager?

Not at all. The Desktop Window Manager has become an integral part of Windows since Windows 7, which is important for creating graphical user interfaces. During the Vista era, Desktop Window Manager was controlled by a service that you could switch off and then turn off all visual effects. This integration is further enhanced in Windows 8 and Windows 10. Fortunately, Desktop Window Manager is becoming more efficient at managing resources, so turning it off shouldn’t be necessary.
