I purchased a retail copy of Windows 7 Home Premium Edition which included both the 32 bit and 64 bit discs. I am currently using the 32 bit version on my computer. I am considering using the Update Anytime online to upgrade to Windows Pro.
In the future, if I build a new computer, can I use the 64 bit disc for install, or am I limited to the 32 bit, since I have already used it? If I can use the 64 bit version, can I still use the key provided for the upgrade to Windows Pro for my old computer?
I don't want to upgrade my old computer to Windows Pro edition if I can't transfer it to a 64 bit version I would need for a new computer. Would the correct sequence be to install the 64 bit Home Premium edition to the new computer, then use the key provided by Microsoft for the Pro version update given to me on the 32 bit update?
