I have a version of Windows 7 Ultimate 32-Bit that I had lying around but the product key is lost. I need to install a 64-bit OS to use all 8GB of my RAM I have installed.

I've found that I don't need the extra features that Windows 7 Ultimate has and don't really want to pay the Win7 Ultimate price for 64 bit.

Is it possible to go back to Windows 7 Home Premium but make the jump to 64 bit? I'm not worried about losing data as this is a new PC and I've heard something about doing a "clean install"

Thanks in advance!

There is no migration path between 32 and 64 bit. You will need to do a clean install of windows. You will need to purchase a new product key if you have lost yours.

If you have a product key for Windows 7 Home Premium then you can do a clean installation of the 64-bit version.

Alright, so I'd need to buy a full license of Windows 7 home Premium 64-bit and then I can just do a clean install?

Yes, normally you could use your 32 bit key on the same version of the 64 bit windows, but since you lost your key, you will need a new one. Even if you still had your key, you would still be required to do a clean install.
