Is there a way to restart a Windows service from the command prompt?
Solution:
You can use net stop [service name] to stop it and net start [service name] to start it up again basically restarting the service.
To combine them just do this – net stop [service name] && net start [service name].
There is also a command built specifically for messing with services: sc
