I have actually never bought a non-OEM version of Windows, so I have never dealt with upgrading systems.
The question is twofold:
How does the upgrade process actually work? I definately want to perform a clean install instead of a in-place upgrade. Is this possible?
I currently have a valid Vista Home Premium 32 bit license and want to upgrade to Windows 7 Home 64 bit. Judging from the answer to this question, it is not possible to actually upgrade it, but it seems it is possible to perform a clean install. How does this work? How does it validate the fact that I actually have a genuine Vista license prior to installing Windows 7?
