The file dwmapi.dll is found only in computers operating Windows Vista. It supervises the look-and-feel of the Vista Desktop Manager Application Programming Interface.

Some of the following Dynamic Link Libraries (DLL) listed as dependencies of the file dwmapi.dll are critical to its system and it includes the files msvrct.dll, ntdll.dll, gdi32.dll, advapi32.dll, and uxtheme.dll. The file dwmapi.dll is also responsible for synchronizing Internet Explorer 7 Graphic User Interface with the desktop theme of Windows Vista. It does this by using the function DwmExtendFrameIntoClientArea that decides which frames are to be rendered opaque and which ones are to be rendered transparent.

Pixels rendered on the screen by Windows Vista desktop composition are different from previous Operating System (OS) themes of Windows Graphic User Interface. The file dwmapi.dll, through its parent program Desktop Window Manager, calls on video memory instead of display devices to draw individual windows before they are rendered as desktop image. Features made possible by this detour include higher resolution support as well as the treatment of windows, icons, as well as other desktop widgets as 3D objects.

The file dwmapi.dll is basically the essential enabling process for Desktop Manager. This is because it is from the file dwmapi.dll that the responsiveness of captioned buttons is tested, the effect of borderless windows is rendered, and it is where the placeholder for color format is located. Moreover, the file dwmapi.dll has attributes for the duration of extant frames as well as the number of background window refreshes that is stored. This attribute, thereby, contributes by enhancing resolution clarity. Thus, it is through the file dwmapi.dll that the Graphic User Interface is visible.

The file dwmapi.dll, that can be located at the path C:// WINDOWS, has a known file size of 37, 376 bytes, which is deemed to be low. The file dwmapi.dll is a more reasonable trade-off since it can perform a larger number of tasks as against its lower file size.
