Using the Resume-Service Cmdlet
Resuming a Paused Service
The Resume-Service cmdlet is used for resuming a service that is currently paused. (What’s the difference between a paused service and a stopped service? A stopped service drops all existing connections and refuses to take any new connections. A paused service will typically continue to service existing connections, but will not accept any new connections.)
To resume a paused service call Resume-Service followed by the service name (that is, the name of the service as stored in the registry):
Alternatively, you can add the -displayname parameter and resume the service using the service display name, the name that appears in the Services snap-in:
Resume-Service -displayname "telephony"
