I recently got an automatic Windows Update, and since then everything either doesn't open or open extremely slow. Firefox works as if nothing is wrong, but trying to open any Windows Explorer window that leads to anything that's not just a normal folder causes the explorer to freeze up and either not respond for a long time, or just stay locked up. I've tried restarting the explorer and that didn't help. I can't even get into System Restore a second time, because the first time I did it I only went back to a time before I restarted to apply the update. I noticed iTunes doesn't open (yet opens in the task manager?) and Skype infinitely tries logging me in.
