So what is it?

Desktop window Manager (Dwm.exe) is an integral part of the Windows Manager, and it gives you a great effect with Vista (Win7): Set the transparency of the form, the dynamic taskbar preview, or even the 3D task switch.

The operating system records just the window somewhere in memory, and the system creates a "composite" view of all the current screen windows before it is displayed to the screen. Because the system keeps track of the context of each window, Dwm.exe can add some effects when the window is arranged hierarchically, such as our usual transparency and dynamic thumbnail previews.

The advantage of using this feature is that the system can take advantage of the hardware acceleration features of the graphics card to create very smooth animations for window minimization and recovery, as well as transparent effects.

What is the use of memory?

If you open up your task Manager, you can see that the dwm.exe process is in the list, and in my tests, I usually take up somewhere in the memory 30-50MB:

Because each window needs to have a buffer in memory to store the context of the window, the memory size of the Dwm.exe process is controlled by the number of windows you open. If you open a large number of Windows, Dwm.exe will consume more memory. In most cases, using a composite window manager is worthwhile compared to taking up a relatively small amount of memory.

The answer is no, just switching to the basic theme (Theme) does not turn off the dwm.exe, but it can reduce a lot of memory usage.
