I'm not sure if it was even mentioned in the "more information" link attached to the update.

I know that if I was in better health and had the energy to do so at the time I learned of this, I would have personally made the effort to verify the malicious behaviour on a clean installation (I got so far as looking up the appropriate law in my country to determine that Microsoft's actions here did appear to be in breach of the UK's Computer Misuse Act), and attempt to see them prosecuted for it, since I strongly believe that they undermined the user's very efforts at securing their systems.

I had a good giggle when I noticed that Windows NT 6.1 ("Windows 7") setup makes password hints mandatory.

I used a password hint of "aye, right!", but I can only imagine the number of poor sods who just type their passwords there (that's the optimal hint, after all...).
