I'm planning on building a new PC in a few weeks with Windows 7 Professional as the OS. The PC I use at the moment has Windows Vista 32-bit edition, since my CPU is 32-bit only.
The new PC is going to have a 64-bit processor, and I wish to have the 64-bit windows 7 run on it.
Right now I'm confused as to what kind of Windows 7 package I need to purchase given my circumstances.
Will I need to purchase the full edition of Windows 7 (non-upgrade)?
Or can I just purchase the upgrade version of Windows 7, install the 32-bit vista version on the new PC and then upgrade from there?
The confusing part is that, from reading the FAQ, I need to do a custom installation if I want to upgrade from 32-bit vista to 64-bit 7 - and at that point, it's no longer an upgrade.
For reference, I'm purchasing from this page: Windows 7 Student Discount
