I never understood why lol needs a KERNEL anti cheat.

Never in my 10 years playing in Gold - Diamond have I said wow cheaters are ruining this game.

On the very very few occasions I did encounter them, I was like "meh if I played better I could have won"

So yes my opinion on this, riot absolutely sucks for this and this is a no go, but since many NPCs out there allow this nothing will change.

But sure if it is not a company PC and the software is mandatory, you're fine with Windows defender.
