Windows 7 Professional to Windows 7 Home Premium?

I have a laptop with Windows 7 Home Premium (64-bit) installed and am planning on upgrading it to Windows 7 Professional (64-bit).

I would like to know if it is possible, however, to revert back to Windows 7 Home Premium (64-bit) once I have installed Windows 7 Professional (64-bit)?


Solution 1:

No, you won't be able to, you'd have to do a clean install. Can't think why you'd want to go back though, Professional only adds features.
