I was just on facebook advising an old classmate on the Win10 Upgrade and a thought came to mind. When Win10 is installed it saves the old Windows folder, renaming it "Windows.old"
If you wanted to go back to say Win7, could you reverse the naming process, reboot you system and have Win7 back again (with the correct registry information intact). Wouldn't that basically nullify everything installed by the Win10 upgrade?
