I have a Windows 7 system that was configuring updates. It got hung at 32%. I hit ctrl+alt+del hoping for the logon screen but instead it started reverting changes. I let it run overnight and when I checked in the morning it was stuck at the same place. I have rebooted several times, tried safe mode but I can't get past this screen. I did take the HDD out and connected it externally and I can see all the data and the files. Is there a file to rename, a command to run or something I can do to get this system to boot?
