bleh - windows update scare

Fortunately it fixed itself, but my newish computer wouldn't turn on after it updated this morning - power and fans but nothing else. I let it cool down, tried again a few times and finally it fixed itself. And then it told me I had to register windows - which I've already done, good thing the box was still to hand. I thought it might have messed up something important and all my programs would be gone. It didn't help that the computer has been off for 2 weeks while I was away. I found the last update and searched online and apparently this is a windows7 64 problem with this update - some people had to get in and manually remove it (not easy if it just won't turn on). {tentative} it seems ok now.
