As per the your query let me tell you that you can not upgrade both the PC with the help of the Single Windows 7 upgrade DVD. The single Windows 7 upgrade DVD can be used to upgrade the single machine only. You can not perform the upgradation of the multiple PC together. If you want to upgrade the another PC then you have to buy one more Windows 7 upgrade DVD.

If you are planning to upgrade both the computer of yours then i will advise you not to but Windows 7 upgrade DVD. Just purchase the Windows 7 family which allows the installation of the Windows 7 on three computers. And also it is of no matter whether you are running the 32 bit or 64 bit. If you like it then buy one for you.
