^ The title pretty much sums it up. I got a laptop for Christmas which had Vista installed on it. I also got a "Free Windows 7 Upgrade" disc as part of the offer, which sounded like a pretty damn good deal. Upgrading to 7 didn't seem like a bad idea, so I installed it yesterday. The installation had three stages: preparation, installation, and finalization. The first two went fine, with no error messages to be found. The third seemed to be going quite well, but as it was going to take a while, I left the room to fix myself something to eat. When I returned, the screen was completely blank, with the exception of my wallpaper. My programs seem to be working in the background, but without Windows Explorer there's no way to access them. Has this happened to any of you guys?
