okay so I'm kinda noob in this case. I just upgraded to windows 10 and still have the option where Microsoft allows you to revert to windows 8.1. I wanted to ask that how to backup this installed version of windows 10 as a backup so that I could revert back to windows 8.1 and install windows 10 again later If I want to? No trolls please.
