Hi, I have a 32-bit operating system of Vista Home Premium, with 3 GB of RAM, and a processor running at 2 GHz. I have passed the system requirements from Windows Upgrade Advisor. I want to upgrade to Windows 7 Professional, but I'm having a difficult time deciding which OS to choose from in Windows 7 Professional. Windows 7 Professional (x86) or Windows 7 Professional (x64)? It's a bit embarrassing, but I'm afraid I don't know the difference between the two. I would be grateful if someone could explain it to me. Thank you.

The 32bit version will work on sytems with 32bit and 64bit CPU's. The 64bit version will only work on a system with a 64bit CPU.
Do you know what type of CPU you have?
