Method #1 - Using [sc] command

Description: Deletes a service entry from the registry. If the service is running, or another process has an open handle to the service, the service is simply marked for deletion. Also the service can be manually stoped then deleted using the [sc] command.
Tip: [service name] is case sensitive, so type the service name exactly as it is.
Usage:  sc delete [service name]

Method #2 – Using [regedit] command

• Open Registry Editor (type regedit in Run window)
• Navigate to: HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services
• Locate the service you want to get rid of and delete its KEY.
