Use may be normal, as was the case on the Windows 10 computer we tested this on, or too high. Too high means that you will see constant or higher than usual cpu and memory usage.

The description simply repeats the name of the process which is not helpful in finding out why it is running.

While the full functionality of the process is unclear right now, it is linked to the desktop background of the system, or more precisely, to the automatic color changing of interface elements based on the wallpaper’s dominant color.

Users of Windows 10 who reported these issues managed to resolve them by turning off the automatic color changing based on the wallpaper. Note that the feature is enabled even if you only use a single wallpaper.

To resolve it, do the following

start color

  1. Tap on the Windows-key, type Settings and hit enter.
  2. Navigate to Personalization > Colors.
  3. Turn off “Automatically pick an accent color from my background”, and select a static color instead.

You should notice that cpu and memory go down after the change. There may be more to the process than just that but making the change fixed it on several systems that ran into the issue in the past.
