I bought Vista 32 bit quite a while ago and had it installed on my old PC. I then bought a new PC about a month ago that already had Vista 32 bit installed on it. I've just bought 4Gb of RAM for it and was hoping to upgrade to Vista 64 bit. I came across http://www.microsoft.com/windowsvista/1033...ia/default.mspx which seems perfect for me. The only thing is that since i my retail version of Vista 32 bit installed on my old PC, I'm guessing the product key will be tied to my old pc right? Should i phone up the Phone Activation thing and get a new key (and if so will my new key work for the Alternate Media exchange)? Thanks in advance Sorry if this is in the wrong forum
