Just want to shared my experience "adventure of installing windows 10," first I install windows 7 (clean install format full drive and of course it was pirated version of windows 7) then I download windows media creation tool from windows official site. install it then hit on upgrade (you need good internet connection because it's gone download windows 10 (almost 4 gigs)) and then it's says your windows 7 is not genuine it's trail version if want to install windows 10 enter your windows 10 key.
So again I start from scratch download another version (ultimate oct-2020 update if I remember correctly) windows 7 (downloaded from different website so different crack(I think it was DLA activated) clean install format full drive). then again download windows media creation tool. install it, open it, hit upgrade, download windows 10, but this time it's works windows 10 install normally. So I check what is say's in windows activation menu it's says windows 10 pro activated by digital license and it's shows an OEM key too.
But one thing for sure there I notice a change in pirated vs genuine windows. in pirated windows there is always some kind process running background you can see system services are using some of your computer resource all the time. but in kind of genuine windows when ideal condition CPU sits on 0%. I don't know how much it gone last long but I'm happy with it
