I just came across the article on Yahoo!
“SEATTLE – Microsoft Corp.’s forthcoming Windows Vista will take much harsher steps to curtail piracy than previous versions of its operating system, including crippling the usefulness of computers found to be running unlicensed copies of the new software. [...]”
After reading the article you will realize that it will do much more funny things than in the past 
But this time Microsoft claims that it is anti-piracy measurements ))) of course…
So finally we came from “It’s not a bug it’s a feature!” to “It’s not a bug it’s anti-piracy!” 
mah wie liab !
