Yeah this reminds me of what happened on tuesday. For the first half of the day windows installed some update and when you restarted it would install and then not be able to load windows at all and then finally a ****ed up windows. The only way to fix it was to use a system restore point and after that I just didn't restart until the box saying it would install a windows update when I restarted went away.. Honestly, I thought it was a virus until my friend said they got the same thing. lol
