Is ProductReview_AccessoryPower the SERVICE_NAME or the DISPLAY_NAME?
The sc command needs the SERVICE_NAME. You can use
sc query
to find out what the SERVICE_NAME for your service is.
One more thing "sc delete" gives this hint:
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.
So you might want to do a
sc stop service_name first before you try to delete it. Wont work of course when there are still open handles to your service.
You'll probably also need to have the proper access rights.
