Using the Start-Service Cmdlet
Starting a Stopped Service
The Start-Service cmdlet is used for starting a service that is currently stopped. To start a service, simply call Start-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 start the service using the service display name, the name that appears in the Services snap-in:
Start-Service -displayname "Bluetooth service"
