How to Start/Stop Windows Color System service

Service name: WcsPlugInService

Display name: Windows Color System


Description:

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.
