So I had win 7 Ultimate installed on my desktop HDD that completely went south and not even close to being able to recover. I have installed win 7 Ultimate on my laptop that was currently running home professional and I used the anytime upgrade and inserted my product key that came with the DVD case. Now this was 3 or 4 days ago and when I inserted the product key, everything seemed to go smoothly. But just now after changing the font & icon sizes, you know how it tells you it has to log off and log back on to change the settings? Well, after I did that a ballon popped up saying I must activate windows or reinstall product number. So maybe I typed a wrong key by mistake. I re-typed the product key and still... No luck. Am I correct for assuming it has something to do with windows 7 ultimate being installed on the HDD that went to Hard Drive Heaven? Can anyone give me some info on what to do? Thank you for your time reading this.
