It's the same patch that us special volume licensing customers (and people who torrent) have been running for over a month
Funny you say that I was about to comment the same thing. Though I hear torrent users got the patch like 1 month before release.
I sort of laughed at the whole "we will stop vista pirates" then all their anti-crack measures apparently failed.
I love reading articles on the war MS vs Pirates always a good chuckle.
