HotCakeX I agree, but in addition: as an "hacker" there is even no need to elevate to Admin/System. It is much easier to just modify your user-writeable Edge-Profile to do the same. Maybe not as persistent as setting policies, but the point is: If you allow malware to run on your system your Edge-Settings are the least problem and you already lost the game.
