Windows 7: Upgrade from Home to Professional

21 Jul 2010   #1

Upgrade from Home to Professional

I hope this is the correct forum to post

I purchased Win7 Professional for my old computer. Shortly after the install my old computer failed. I've since purchased a new computer with Win7 Home.

My question is: can I somehow upgrade the Home version to the Professional version using the Professional Install disc? The old computer was 32 bit and the new computer is 64 bit if that makes any difference.

Thank you in advance, Wally

If it is an upgrade DVD the rule is on one computer only, so yes. I will get you the tutorial showing how.

If your win7 pro is a retail copy, you can also simply do an Anytime Upgrade on your Home premium computer, using the Pro key. Keys are not architecture specific (i.e. whether 32 bit or 64 bit). Heres a tutorial.

Please first make recovery dvds on the home premium computer or save a system image using Macrium Reflect, that way you have the option of reverting to Home premium if you wish to. Then follow the Anytime Upgrade guide.
