What does Windows Cannot start this hardware device because its configuration information in the registry is incomplete or damaged code 19 mean?

The primary reason for Error Code 19 to happen is when more than one service is set for one drive, and there is a failure to open the service key or retrieve the service key from the driver. When I say Service Key, it means that the driver has a key to the form-
