Vista to automatically revoke activation?

I stumbled upon an interesting article about a specific behavior of the Windows Vista operating system where a blog author described an unusual behavior that he was experiencing while running the operating system. The Windows Vista version in question was fully activated and genuine, and the issue started to appear after installing a version of the upcoming massively multiplay online roleplaying game 9 Dragons. The game was in open beta at that point in time.
The game started up normally and the author was able to play it for a while. Suddenly, the game was minimized while the author of the article played it and a notification by the Vista operating system popped up instead. The message that was displayed on the screen told the player that the copy of Windows Vista that was in use was not genuine.The attempt to reactivate the operating system failed, even though the correct key was supplied during the process. The operating system and Microsoft's servers somehow would not accept the product key anymore even though it had been accepted before as the system was activated before.

I am playing the game when all of a sudden I get popped out of my game back to desktop with a message that my copy of Vista isn’t Genuine. Now I have the reciept, the box it came in, and the hole in my bank account to prove that I do indeed have a legal copy. It turns out that if you install a program your copies of Windows Vista will unactivate itself. I am livid, where does Microsoft get off telling me what I can put on my personal PC? I have been a Wintel network administrator going on 11 years now, and this just seems so over the top.

It was only after uninstallation of the9 Dragons game that the attempt to activate the Windows Vista operating system was accepted.

If this story really holds true it is a remarkable one. Why on earth would Windows Vista revoke the activation - this would be the main questions that would have to be answered.

This looks like a way for Microsoft to revoke the activation on systems that run known pirated keys or install software that would probably try to interfere with Windows Vista core processes.
