This is managed Windows services
Window Services is a process that is managed by SCM(Service Control Management) of Windows O.S. The service managed by SCM includes kernel driver but those are not managed by MCCS agent.
Commonly, it can be used when dealing with package software like MS-SQL or Oracle DB.
