You lot really are clutching at straws. Why on Earth would MS do that? Of what possible benefit would it be to them?
The truth is it's only support for MSE (Microsoft Security Essentials), their anti-virus product, and MSRT (Malicious Software Removal Tool) that has been extended. Nothing more.
I particularly liked this "I still think it's beholden on Microsoft to provide some sort of inexpensive update subscription for all XP users". C'mon guys, you've had how many years notice that this was coming? Five!!!
It
is the last moment so get on with it!
