Kernel mode means the cheat reads game memory from ring0 instead of hooking the game .exe like old trainers. Less obvious, harder to block, more stable FPS.
Your loader installs the driver once per session. Reboot clears it unless you set persistent install — most users shouldn't.
BSOD after inject usually means conflict with another driver — antivirus, old cheat leftovers, or RGB bloat.
Stick to one kernel provider. Running two different Fortnite cheats same week is how people brick boot times.
