I have upgraded windows with a (False) Upgrade key to Microsoft Windows 7 Ultimate. I was currently on Microsoft Windows 7 Premium, But now it says I have to activate again. (Microsoft has blocked the Product Key) So.. I would like to downgrade back to my old one so it's legal. *So my question is. How do I downgrade? (I recently tried clicking Activate Windows Now. And I then typed my Product Key, but then it said "Try Windows 7 Setup or Type a Windows Ultimate Product Key") Any help on this maybe? Anyone know about this? Thanks in Advance Tom.
