This function returns the handle to a service instance based on its prefix.
This function is deprecated. To obtain a service handle, call CreateFile with the same prefix of the service whose handle must be retrieved.
Note
Do not use CreateFile to get the service handle if DeregisterService is called to unload the specified service. In this case, call GetServiceHandle to obtain the handle.
