Default Description
Enables relative prioritization of work based on system-wide task priorities. This is intended mainly for multimedia applications. If this service is stopped, individual tasks resort to their default priority.
Additional Information
This service is required only for the fact that Windows Audio service lists this as a dependency. Without the Windows Audio service, no audio will be played on the system. This service is started upon system boot, but shortly after (~ 8 minutes), it stops. A nice change from Windows Vista.
