The Desktop Window Manager is a software component of Microsoft Windows. It is the successor to the Desktop Composition Engine, starting from Windows Longhorn build 4066.

It is used to render UI elements, animations, and visual effects (such as desktop star effects in build 4066 and 4074 and Windows Aero transparency and animations in Windows Vista and Windows 7). By default, the rendering pipeline will use the system's GPU if possible (through the DirectX API), but starting from Windows 8 build 7927, it will also render using a software-based 3D rasterizer when such an accelerator is unavailable.
