A while ago I was given a German Windows Vista Ultimate (both 64bit and 32bit on separate disks) during a Micosoft promotion event. Now I am not sure what kind of version I got here (maybe you can help me out). On the disks is written that it includes Windows Anytime Upgrade and that I am not allowed to resell it. There is also an item number on the disk: X12-73442-01 (64bit) and X12-73358 (32bit). Would I be able to upgrade to Windows 7 Ultimate with this? How could I find this out? How much would it most likely cost me (germany)? I have never installed these disks anywhere. How can I make sure I don't buy an upgrade only to find out that it is not working with my version of vista. Also, it seem that a there is no specific sytembuilder ugrade. In case my version is a systembuilder version I would come cheaper buying a full systembuilder windows 7 ultimate than buying a window 7 ultimate upgrade. I can't upgrade vom system builder windows vista to full version windows 7, can I?
