Windows Color System (WcsPlugInService) Service Defaults in Windows 7
The WcsPlugInService service hosts third-party Windows Color System color device model and gamut map model plug-in modules. These plug-in modules are vendor-specific extensions to the Windows Color System baseline color device and gamut map models. Stopping or disabling the WcsPlugInService service will disable this extensibility feature, and the Windows Color System will use its baseline model processing rather than the vendor's desired processing. This might result in inaccurate color rendering.

Default Behavior
Windows Color System is a Win32 service. In Windows 7 it won't be started if the user doesn't start it. When the Windows Color System service is started, it is running as NT AUTHORITY\LocalService in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If Windows Color System fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the WcsPlugInService service is not running because of the error.
Dependencies
Windows Color System is unable to start, if the Remote Procedure Call (RPC) service is stopped or disabled.
