To use it in a run script and get feedback we need to delay the restart of the service using scheduled task

Thanks @PotentEngineer and Russ for the code I mismashed together
After running the Script it is not possible to force timed restarts..
It can't find the biggest active service window....
The script stops the whole SCCM service for that session
