They will only work to install windows 10. To properly activate windows 10, you have to first upgrade from an activated version of windows 7, 8, or 8.1 and then after successful upgrade, do a clean installation of windows 10. FYI: you can choose to skip the product key when installing windows 10 with clean installation and it will be activated automatically if you previously upgraded to windows 10 from windows 7, 8, or 8.1 on same computer. Basically these keys are just used for installing or if you want to change your product key after windows has already been activated. :) Questions? Twitter: @simpves
