Can I upgrade Windows 7 Pro Retail to 64-bit later on?

post #1 of 10
Thread Starter 
If I had the full version of Windows 7 Professional and installed just the 32-bit version, could I later uninstall my system to upgrade to the 64-bit version on the second included install disk?

Yep, it doesn't matter weather you install the 32 or 64 bit as long as it's still Win 7 Pro

Bear in mind you can't upgrade from a 32-bit O.S. to a 64-bit one. You'll have to do a clean installation.

Yes you can as long as you still have the 64-bit disk with you. However as grss1982 has mentioned, you will need to drop the nuke on your hard drive (AKA Reformat) in order for you to get it installed into your system.

Be sure to back up your important data files before you decide to wipe the HDD and upgrade to 64 bit system. Also do take note that you will need to discard (almost) all of your 32 bit drivers as they are incompatible with the new 64 bit.

Second question: How good is Windows 7 64-bit compared to Windows XP x64 bit with using 32-bit programs? I know 64-bit windows can't use any 32-bit drivers at all, but is Windows 7 64-bit just as bad as x64 bit Windows XP was?

IN between XP and 7 there was also Vista 64-bit...So I'd hazard I guess that 7 should be a lot better.

Windows 7 x64 is great at running 32bit progs. I've never had any issues running them, and I started with vista x64. If anything, you can just run a VM with a 32bit OS in it.

How about with using older hardware, like a printer?
They do not work without a 64-bit driver?
