Just went to download the patch on my Linux box. They request windows validation to download it. I presume the code I last got has timed out and I could go to the trouble of getting a new one, but how wrong. I don't use Windows online but I considered methods of getting it for my sister and for offline machines. Microsoft say security patches will be provided even to known pirate copies for the protection of all users from bots but I've also found friends non WGA systems that needed big kicks to get them to update.

To the comment about not targeting wndows update, the linked article says this.

"The full mechanism isn't yet completely analyzed, but Flame has a module which appears to attempt to do a man-in-the-middle attack on the Microsoft Update or Windows Server Update Services (WSUS) system"
