It doesn't matter if it's hard if u can't understand that, i have both of windows genuine and if u didn't used win10 before u prob will regret it for using it and will return to older w7 same as most of people use Win7 due not to having money to upgrade but better perfomance/stability and not new gen things from microsoft that creates so much input lag in all games? If u can't understand or help to use W7 with this game then don't speak.
