I seem to have developed a major issue with my PC. I'm running windows 7 home premium. Approximately 3-4 weeks ago when windows starts it does a configuration of updates, after trying to load for several minutes it says windows configuration failure, reverting changes please do not turn off your computer. I eventually had to turn pc off manually because windows never did boot. I was able to do a system restore a couple of times but now I cant do that. I've tried a system repair in command prompt but this didn't work either. I can't get in to windows update under the start menu. Nothing seems to be working. I can use my PC in safe mode or safe mode with networking. Don't know what else to do. My machine did not come with recovery disk or windows disk. I wonder can I use an up grade disk? Just curious.
Hope someone can help
