Hi,
Based on my test, this service will stop after 10 minutes. It is by design.
It is supposed to start automatically when the service needs to be used and configured the startup type as Automatic.
But per further searching, some people shared following method to keep the service running even when idle. Kindly have a test and let us know more assistance needed.
Key : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\RemoteRegistry
Name : DisableIdleStop
REG_DWORD, data : 1
Note: No restart should be required. And always backup important data before changes made in registry.
Hope this helps and please help to accept as Answer if the response is useful.
Thanks,
Jenny
