I got back from an overseas trip in March. Every time I tried to run Windows Update in "batch" mode - doing them all at once, my Dell XPS 420 Win 7 x64 not only hung on reboot at "configuring Windows 32%" - it crashed with the blue screen of death. Two cycles through safe mode boot up/regular boot up (reversing the updates) and one more BSOD later, I was back where I started. After days of experimenting (thanks Microsoft, I had nothing better to do) I figured out it was KB2862330 that was the problem. I hid it and ran all the other updates. First one at a time, then all at once. They worked. I'm glad that worked because I was about to despair and do a clean install of W7 x64 ultimate - which would have wasted another bunch of hours, for sure.
When I was trying KB2862330 and failing, I had NO usb devices plugged in (noted that someone else here thought that was the problem).
Then I searched forums for comments on KB2862330 and found that it first came out last fall and crashed a bunch of computers. Then it was "fixed" and reissued in mid January 2014. Well, it may not kill all Win 7 x64 systems, but it sure won't work on mine. So I'm leaving it hidden. I'll read what it was supposed to fix (apparently an insecurity in usb ports) and try to protect my computer another way.
So my solution - wait until Microsoft fixes it for real - and then be sure to try it all by itself.
