Change Windows 7 Edition after install

Change Windows 7 Edition after install - Super User



There is a way. See Downgrade: Change Windows 7 Ultimate to Premium or Professional. I successfully downgraded from an unregistered Ultimate to a registered Professional edition using a universal installation DVD. You edit two registry keys to match the edition you want, then use the DVD to "upgrade", without booting from the DVD.



Here are the two keys to modify:



  • \HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EditionID: change from Ultimate to Professional or HOMEPREMIUM
  • \HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProductName: change from Windows 7 Ultimate to Windows 7 Professional or Windows 7 HOMEPREMIUM
