Do you guys think this method will work to upgrade from Vista Home Premium to Win 7 Professional? I am afraid to try since I might crash the system which would defeat the purpose of the upgrade vs. a clean install.

Is it possible to upgrade from Vista Ultimate to 7 Enterprise/Professional with this method?

I just tried this but didn’t work. Error message said “You can not upgrade from enterprise to ultimate, you need to reinstall”…

I forgot to say I was using Vista Enterprise with SP1 also. I DID NOT have to uninstall SP1 first.

Also works for upgrading Vista Enterprise to Windows 7 RC .
Do the same just to get Windows 7 installing, change the EditionID an ProductName to Business and re run the setup, there you go now is installing.

Good luck!!

Thanks a lot for this amazing solution, I really needed to upgrade my vista to ultimate so I can upgrade to windows 7, I have adjusted the Registry first then uninstalled SP1 then restored the pc to an earlier restore point then the upgrade worked .
