I had Windows XP 32-bit. Bought Windows 7 upgrade and upgraded to Windows 7 32-bit. Then I noticed that there were two disks and that my processor (Intel Core 2 Quad Q6600) is also 64-bit ready.
What are my options?
Can I still upgrade 32-bit Windows 7 to 64-bit using the upgrade disks that I have? I'm ok with wiping everything and reinstalling everything from scratch, I just don't want to pay for new copy of Windows 7 again. (btw. I already did register the one I'm currently using)
