Windows Color System (WcsPlugInService) Service Defaults in Windows 8
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 8 it will not be started until the user starts it. When the Windows Color System service is started, it runs as NT AUTHORITY\LocalService in a process of svchost.exe, sharing it with other services. If Windows Color System fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the WcsPlugInService service hasn't been started.
Dependencies
Windows Color System can't start, if the Remote Procedure Call (RPC) service is disabled or not available.
