What is the process of dwm.exe in Win7 system? How to turn off dwm.exe

When using Win7 system, when the user opens the task manager, you can see that the dwm.exe process is running in the process list. I don't know what process dwm.exe is. what's the effect? Then let's take a look at what process dwm.exe is in Win7 system, how to turn off dwm.exe.

So what is it?

Desktop Window Manager (dwm.exe) is part of the window manager, which gives you a great effect on Vista (with Win7): setting the transparency of the form, dynamic taskbar preview, and even It is a 3D task switch.

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

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

How is the memory used?

If you open your task manager, you can see that the dwm.exe process is in the list. In my tests, it is usually somewhere in the temporary memory 30-50MB:

Because each window needs to have a buffer in memory to store the context of the window, the amount of memory occupied by this dwm.exe process is controlled by the number of windows you open. If you open a lot of windows, dwm.exe will take up more memory. In most cases, using a composite window manager is worthwhile compared to using relatively little memory.

Switch to the basic theme to turn it off?

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

So how do you turn off dwm.exe?

Unless you're playing a full-screen game, I don't recommend turning it off, and it doesn't necessarily increase the speed. The only way to turn off dwm.exe is to stop the service from running. Open “service” in the control panel or the Start menu, then find the “Desktop Window Manager Session Manager” in the list, then click the “Stop” button. Note that after clicking the “Stop” button, you will Switch to the basic theme of the system (Basic Theme).

If you want to disable it permanently, double-click it and select "“Disable" in the drop-down box of "Startup Type";

If you want to use the command line, then You can run the console in admin mode and use the following command:
