is their a way to go back to windows 7

 i remember when windows 10 used to have a option to go back to windows 7 (or windows 8 or 8.1 mostly 7)

currently i have windows 10 build 1903 and os build 18362.1139

plus windows 7 is cool and i cant find any download or os download

(plus plus im broke and my pc dont have a disk drive i have a lap top)

please make it so you can do it again

(PS: my pc came with windows 10 so does that mean i cant downgrade)

the end
