Hi all, I just bought a new HP laptop and Win7Pro upgrade disk is available with the purchase. I'm a new Win7 user and still playing around with it. I successfully activated the key. A question came to mind though, I know the upgrade disk only allows a few times (3?) activation using my current key. In the pas when I was still using XP, I tend to format and clean install an OS every now and then. They didn't have activations back then and I could do this infinite amount of times. So, now that the new Win7 has a limit of installs/acitvations on it, does that mean I can't format my PC more than 3 times? What if I get lucky and attacked by viruses 3 times that led me to formatting my PC. Does that mean I have to kiss my genuine win7 goodbye??? I'm not sure how the activation system works. Please let me know how it is. THanks!
