I used to use TweakUI to hide a drive containing some personal information. All of a sudden the drive is now showing in Windows Explorer. I've tried uninstalling it and reinstalling it and that didn't help. I also tried to hide it using the Registry Editor and adding a new DWORD "NoDrives" but that didn't work either. There was already one there, I assume from TweakUI so I deleted it and created a new one but the drive is still showing. What could have caused TweakUI to suddenly stop working? I had some weird issues with my BIOS, but shouldn't TweakUI still work?
