Windows 7: Moving from 32-bit to 64-bit

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 Windows 7 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 Windows 7. 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 Windows 7 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.
