Windows Color System

The Windows Color System (WcsPlugInService) service hosts non-Microsoft 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. The Windows Color System system provides for more precise color mapping and gradation. Non-Microsoft vendors such as printer manufacturers and photo finishers can use this feature in applications and drivers to explicitly call the color that they want rendered.

Stopping or disabling the WcsPlugInService service disables this extensibility feature, and the Windows Color System uses its baseline model processing rather than the vendor's requested processing. This might result in inaccurate color rendering.

This service is installed by default and its startup type is Manual.

When the Windows Color System service is started in its default configuration, it logs on by using the Local Service account.

The Windows Color System service is dependent upon the following system components:

  • Remote Procedure Call (RPC)
  • DCOM Server Process Launcher
  • RPC Endpoint Mapper
