I have two Dell computers that came with Windows 7 Pro 32-bit edition (with OEM licensing).

Can I upgrade them to the 64-bit edition using a Windows 7 Pro 64-bit retail Upgrade disk?

Is their a cheaper way to do this (I.e. can I just call dell and get them to send me a link to a Windows 7 x64 Pro .iso with OEM licensing)?

This question came from our site for professional system and network administrators.

    
Looks like I answered my own question. Per a dell service rep, the OEM license does cover both 32 bit and x64 editions. He said to just use the Windows 7 Pro x64 disk I had from another Dell computer to install on the 32 bit machines. –  user426724 Sep 15 '11 at 15:58

Note that you can't upgrade from x86 to x64 regardless - it requires a clean install. The Dell disk should handle it fine, though. –  Shinrai Sep 15 '11 at 17:00
    
Borrow a Dell branded W7 Pro 64bit install disc from a friend, neighbor, clasmate, or co-worker, this is the cheapest way. –  Moab Sep 15 '11 at 18:44

As you said, the key doesn't matter when it comes to x86 vs x64, only version like Home Professional, Pro, Ultimate.
