To test a device driver that I am working on, I added a registry key to the HKLM\Drivers\BuiltIn.
I want to delete this registry key now. But when I try to delete I get the error: Can’t query key 'Drivers\BultIn.
I renamed my registry key to some other name and then deleted it this time it worked, saved the registry and restarted the system. Yet after the boot up my original registry key showed up under the Drivers\BuiltIn.
I also tried Clear registry option yet after resetting the board my registry was there at the same location.
