Windows Server: Code 19: Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged

Hi everyone

If you happen to come accross this error it can have multiple cause.




– Re-installing the driver does NOT fix the error.

– Erasing and to let the system to re-install does NOT fix the error.



– Check in the registry under : HKLMSYSTEMCurrentControlSetControlClass and find the device that give you problem. In my case it was a Tape Driver, so I looked in each Class to find the description matching the error.



– In the correct device class erase the LowerFilters key


– Restart the server


Now it should work !
