OK, so, four days ago I started to notice that after an update, several of my metro apps would not open. I tried running all the troubleshooters and solutions, but nothing worked. Yesterday I gave up and decided to do a Refresh on my laptop and just start over. I was trying to update it so that I could get it to Windows 8.1, but now it's stuck in a failure loop and I don't know what to do. It just says, "Failure configuring Windows updates. Reverting changes. Do not turn off your computer." It's restarted twice, but I can't do anything. It boots and then goes right back into the failure message and I can't get to an active screen anywhere. I tried F8 but it didn't work.
