Is anyone familiar with how the hardware drive region is set so as to report correctly?

According to the hardware properties page for the device, within the Windows Device Manager, it is currently set to Region 1. I could not find any additional method of changing the region --- other than the software settings and emulation within AnyDVD (where it currently shows that I'm using Default Region 1 US; all other options on that page are 'checked').
