The '''Desktop Window Manager''' (in early [[Windows Vista|Longhorn]] builds known as '''Desktop Compositing Engine''') is a software component of Microsoft Windows. 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]]), drawing the non-client area of every top-level window. By default, the rendering pipeline will use the system's GPU if possible (through the DirectX API), but starting from [[Windows 8]] [[Windows 8 build 7880|build 7880]], it will also render using a software-based 3D rasterizer when such an accelerator is unavailable.
桌面窗口管理器(在早期的 [[Windows Vista|Longhorn]] 版本中称为 Desktop Compositing Engine,即“桌面组合引擎”或“桌面合成引擎”)是 Microsoft Windows 的一个软件组件。它用于呈现 UI 元素、动画和视觉效果(例如 Build 4066 4074 中的桌面星形效果以及 [[Windows Vista]] [[Windows 7]] 中的 [[Windows Aero]] 透明度和动画),绘制每个顶级窗口的非工作区。默认情况下,渲染管道将尽可能使用系统的 GPU(通过 DirectX API),但从 [[Windows 8]] [[Windows 8 Build 7880.0.fbl_grfx_dev1.101110-1700|Build 7880]] 开始,当此类加速器不可用时,它还将使用基于软件的 3D 光栅器进行渲染。
