WPA crash vista???

Okay. I need help since I barely use M$ any more, the last time I used it for something other than school, work, or AIM was back in the days of WIN98. I was just reading the article on this site, Is Microsoft about to release a Windows �kill switch�? | Ed Bott's Microsoft Report | ZDNet.com, and I have a question about it. Does this only apply to XP or to Vista as well? Because my friend just had her first "Blue Screen of Death" attack and is scared that she destroyed her computer. I have yet to know if it happened right after security updates or not, but I know she has auto updates so it would have done it itself.
Any help would be appriciated.
