There you go. MS manages to mess up their last good OS.
That is why I am not updating (that and I haven't booted windows up for quite some time)
Personally, I had to uninstall Alcohol 120% before SP3 would even install. (It somehow locks up atapi.sys) It was a bit of a pain to find the source of the problem in the knowledge base, and I imagine the problem would have been a total deal-breaker for anyone who isn't a geek.
I have installed it on around 12 machines with no problems.
