I recently purchased a (used) gaming laptop which originally came with 8.1, but it was terrible to say the least even tho I did a fresh format and full install of 8.1 when I got it. Driver issues, crashes, hangs and freezes, especially on the sign in screen. Even start up repair was total crap. I decided I would rather have a 30 day trial of 10 than reinstalling windows hate.1. LOL. When I did, it says windows is activated, never even asked for a key. I go to system and it says windows is activated, does that mean it is for good? Maybe my Asus had a free upgrade? both editions (8.1 and 10) were home by the way.
