Desktop Window Manager in Windows 10

What is DWM.EXE?

Desktop Window Manager (DWM, previously Desktop Compositing Engine or DCE) is the window manager in Windows Vista, Windows 7 and Windows 8 that enables the use of hardware acceleration to render the graphical user interface of Windows. It was originally created to enable portions of the new “Windows Aero” user experience, which allowed for effects such as transparency, 3D window switching and more.
