I recently updated my Windows 7 x64. Before the updates, everything was working correctly, no issues. After updating, my keyboard's Windows key is not working and neither are its shortcuts. I checked it with KeyTest - button is not working. I tried to locate Scanncode registry, but I found nothing. I also tried to remap the Windows key hoping that Scancode Map might reappear, but no luck.

I am using the Aero theme and my graphic card is HD radeon 7870.
