System services are basic system programs and very important for Windows operating systems. Especially programs which shall run without any user activity are implemented as a system service
in the most cases.
The system service monitor works similar like the application monitor that means you can define white and black lists for system services.
White list means that you can be sure that a service is always running (i.e. the anti virus service). If the service does not run CheckSystem is going to start it automatically.
Black list means that you can be sure that a service does not run (i.e. the telnet service to prevent hacker attacks). If the service is running CheckSystem is going to stop it automatically.
With help of the system service monitor you can decide and limit which service might be run and which not.
