All of the steps he described are unnecessary.
I had a CS:GO cheat in my drive for about 6 months while playing Fortnite, and suddenly after an update, it wouldn't let me jump out of the bus. I just removed the SSD with the cheat and without even reinstalling windows i was able to play fortnite again. Thats why always have your cheat on Flash Drives. It was very fast, 1) close pc 2) unplug SSD, 3)open pc and play fortnite
