Usually when you uninstall something associated service is removed with the software, but sometimes its not.
In order to remove service manually you need to:
- Click “Start” -> “Run…” -> type in “regedit”
- Find the registry entry
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services - Find the service you need to remove and delete the entry.
Note: Check what files are used by the service as you might also want to remove them. - Restart Windows.
