[SOLVED] HWID Spoof all your HDDs, Motherboard ID/FW etc and then re-install Windows, install Epic Games launcher onto an External HDD both the client and the game itself "Fortnite" all onto your External HDD and then launch the game, you should see the small game banner appear with Anti-Cheat loading up before the game does and you're all done , you're very welcome.
P.S. Don't play on the same account that got banned, this is just a method on how to be able to play the game again on the same PC (removing the machine ban that Epic Games places onto your PC)
