Moving from 32-bit to 64-bit

I'm looking to buy a PC that comes with Windows 7 Pro 32-bit pre-installed. I want to wipe that and do a fresh install with 64-bit. First, will the license work with both? Second, how would I go about getting the 64-bit version?

If you want 64 bit it's best to just buy one with 64 bit. You wouldn't have to buy a 64 bit version. The Microsoft anytime upgrade may or may not work with an OEM version (what new PC's come with). Either way you would have to do a complete new install for the 64 bit version.

If you want a specific version of Windows 7, e.g. Ultimate version it best to buy it with that and pay the extra to the PC Vendor for the upgrade.

Every Win7 license can be used with either 64 or 32 bit. It's in the EULA which means even your computer manufacturer can't override it.

Obtain a 64 bit copy of your version Win7. All versions are in every installer but some need unlocking by deleting ei.cfg file in Sources folder. Then recompile ISO to burn all-versions DVD,

Greg, are you sure that's going to work. Because I want to go the other way with my newly aquired laptop - hate the 64bit. None of my pet programs run. And I have a 32bit OEM installation disk that I bought from Newegg and installed it on my big rig. Can I use that to "downgrade"?

Yes, every Win7 license allows the use of either 32 or 64 bit, just not both at the same time.

If you want to be sure in your case, call MS customer service.
