Vista activation cracked by brute force Keygen (update -- or not)

Keznews reports that Windows Vista activation has been cracked by brute force using Keygen. There's nothing clever about this: it just makes about 20,000 attempts per hour until it finds a valid key. Which can take hours or days. The instructions conclude:

DISCLAIMER: under no circumstances should anyone sell the key that they generate. I do not support Piracy, this was simply an experiment in which i used to practice my vbscripting. This was just for fun and was a complete accident! sorry for cracking your beautiful operating system BILL GATES

I strongly encourage everyone to purchase windows vista, and be a genuine customer!

The "valid key" could be one that a genuine customer is already using, so it will be interesting to see how the WGA site handles cracked keys, and how Microsoft responds. It will, after all, have the IP address of most of the naive users who try this.....

Update: A follow-up post now says: "fact is the brute force keygen is a joke, i never intended for it to work. I have never gotten it to work, everyone should stop using it! everyone who said they got a key a probably lying or mistaken!"

There's some discussion at Slashdot.
