I searched the internet a bit and found a small program on pscode.com. This program has the capability to reset the values to what they where when windows shut down. It uses it's own saving file so it is not that dependable on what windows says.
Why not try it. You should use the adminversion because it has the ability to start when windows does and save the settings / reset the settings (and thats what you want).
