Later in the month I'll be helping my dad build his new PC, and I've been leaning towards the Windows 7 Family Pack so we can upgrade all our PCs to Windows 7 64-bit. The only problem with that is the fact that it is an upgrade version. Right now I still have my Windows 7 32-bit OEM CD, so I've been thinking:
Would I be able to upgrade my Windows 7 first, then install the 32-bit OEM version on my dad's new PC, and then upgrade his? If this wouldn't work then I can just tell him to buy a single license HP or Professional, but it'd be nice if we could upgrade all of our PCs to Windows 7 64-bit.
