dwm.exe | Desktop Window Manager | Is It Safe? | How To Remove?

What is dwm.exe?

Dwm.exe is the executable file that runs the Windows Desktop Window Manager.

It is a compositing window manager that helps you get effects in Windows like transparent windows, live taskbar thumbnails, flip 3D, and high-resolution monitoring.

Like most applications, it doesn’t draw the display directly to your screen, but rather the application writes the picture of their window on a specific place in memory. Windows create a composite view for all the screens on the window before transferring it to your system.

Windows simultaneously composites and displays the contents of each window. Then the effects are added like animation and transparency when it layers the windows for display. This application composites the display of the windows application before finalizing it and transferring it to your screens.
