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 is 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? If so how much would it most likely cost me?
