[Curt]: I have never heard of this before. Quite frankly: You are scaring me! Will you (any of "you") please tell what this is about?
After five reinstalls, Vista kills itself and you have to purchase another license and activation key. Worse, if you flash your bios, change something like a videocard or processor, you either have to call Redmond and obtain another activation key, or, you have to buy another copy of Vista when you change too much on your system that Vista is licensed to — it's all in that crazy EULA that drove me to GNU/Linux last year. I torch my system at least once every few weeks, not to mention I build and upgrade my own computers. Vista really put a damper on the enthusiast market. At least they're getting rid of the remote kill switch in SP1!
