Microsoft say NO - every one else says YES....! The updates actually changed registry values, giving mainly a black screen, just with, at most, a small warning message. Windows could not be loaded!
I had the problem on my 3 pc's (2 desktops and 1 laptop) and it took me around 4 days to figure out the problem. I could always load windows by a different method, but very, very long winded. I finally found that by going into the "BIOS" system and revaluating to "original/default values" the problem was solved! In other words all 3 pc's had the same REGISTRY problems after updating from Microsoft!
I'm just surprised that so little has been said about the problem, and I advise you (and myself) to rethink your policy regarding "Windows Updates" and indeed rethink about Windows - in general! Linux is free, Google Chrome o/s is coming out in the near future, whilst Windows are already talking about Windows 8 - S month or so after cashing in on Windows 7 ! Is there any limit to their greed?
Here is an article I found about the problem (You can see the original article by clicking on the title above):
