Hey everyone, Just installed windows vista ultima edition onto my HP lappy and then my new macbook (to take advantage of the t-mobile hotspot offer, free internet in places, ie starbucks, for 2 months if using vista). Well it seems my product key is only good for one account, not the 5+ I was thinking (for 300+ I would hope it would be more than one user). I go to authenticate and it tells me that my product key is already used. So is there any other means than buying a new edition? What happens when my install doesn't verify through windows? Am I wrong in that there are more licenses for ultimate editions? Any suggestions? I hate to complain as I got the windows vista ultimate for only 45 through a friend at microsoft, but to pay more the for the ability to boot into windows is ludicrous and not to mention that I ordered a 160 GB Hard drive so I could put 30 or 40 GB to windows. Thanks in advance.
