This question isn't a duplicate of: https://serverfault.com/questions/420903/upgrading-existing-windows-7-pro-licenses-to-ent -- this question asks if the PC can be upgraded "without rebuilding the whole pc" -- it's not a licensing question. – TheCleaner Apr 13 '17 at 20:34

I honestly don't know if it still works with all of the patches MS put out over the last few years for Windows 7, but you used to be able to trick it via the registry and then do an in-place upgrade.
To try this on a single computer first (one you really don't care about):
- Open
regedit - Go to
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\Current Versionthen change to “Enterprise” in ProductName and EditionID - Start the ISO/DVD of Win 7 Enterprise within Windows and do an in-place upgrade
After the upgrade (assuming it still works this way) reboot and then change the product key to the Enterprise key.

I also just verified this to still work. However, the language of the Windows 7 Enterprise DVD/ISO needs to be the same as the already-existent Pro installation, otherwise the Installer refuses to do the upgrade. – skalarproduktraum Apr 18 '17 at 12:29

Nope. They're completely different in Microsoft world. They are not part of the same licensing path.
