Is a downgrade from Windows 8.1 Pro to Windows 7 Professional reversible?
If I downgrade from Windows 8.1 Pro to Windows 7 Professional, can I change my mind later on and upgrade to Windows 8.1 Pro for free?
Downgrade rights
Quoting the Microsoft website:
If you do have downgrade rights and decide to use them, you continue to keep the license and rights of use for your original version and may "upgrade" back at any time.
