I had Windows 7 Premium (I think that's what it's called) initially on my PC. Ended up reformatting my HD, and installed the wrong version (Windows 7 Home), so only 4GB of my 8GB RAM is usable.

Can I install Premium over the top of this without reformatting again? I'd heard no but want to confirm.

"Premium" isn't the issue. 64-bit vs 32-bit is the problem.

*doh* Sorry, that's what it was...I knew I was flubbing what I was saying. I had the 64 bit installed originally, and now have the 32 bit. Can I install the 64 bit now without reformatting?

I don't think you'll have to reformat, but I think you'll lose everything installed in Windows. Not positive though, I haven't done it. But even the Program Files folders are different so there's a good chance of that.

Yeah, you can't do an in-place upgrade from 32-bit to 64-bit. You'll have to do a custom install. If you don't reformat, the installer will move your 32-bit install (Windows, Program Files, and Users folders) to a "Windows.old" folder.

So...could I technically do the custom install without reformatting, then transfer those files over and uninstall the 32-bit?

If by "those files" you mean user files (documents, music, videos, etc.), then yes, you can do the custom install without formatting, then move those files from "Windows.OLD\Users" to your new user folder. You should, however, have a backup of all important files before the custom install (technically, you should always have a backup of these files).

However, you can't transfer over previously installed programs into the new Program Files (x86) and Program Files folders, you should re-install them instead.

Once you've gotten everything you need out of it, you can delete the Windows.OLD folder. However, you may want to keep it around for a while, in case you miss a file you need on the first go round and don't realize it until later.

Yep, that's what I meant. That's cool...makes it much easier and more realistic to do.

However, you can't transfer over previously installed programs into the new Program Files (x86) and Program Files folders, you should re-install them instead.

Makes sense...so I'd lose all program installations, but would keep my files...I'm good with that.

Once you've gotten everything you need out of it, you can delete the Windows.OLD folder. However, you may want to keep it around for a while, in case you miss a file you need on the first go round and don't realize it until later.
