What happens to my old license when I upgrade to Windows 10?

I am considering reserving Windows 10 for both of my Windows 7 computers. I can only do this if I can downgrade without having to go through a lot of problems. If I get Windows 10 on my machines and I don't like it, can I simply revert by using an older backup? Will my license still work for Windows 7?

To be clear: I am NOT asking how to revert. I am asking if my license will still be legal for a Windows 7 install. I have full system backups. I make them every week. I do not want to go back to a Windows 7 system backup and discover that my license is no longer valid for Windows 7.


Hello 4denise.

Your Windows 7 license will always be valid and will not be changed or deactivated because of the upgrade to Windows 10: you'll be able to install or restore Windows 7 again in case you'll need to do that (provided that you've the Windows 7 installation DVD or a set of Windows 7 restore discs or a full disk image of your PC running Windows 7, of course).
