Core Isolation- Memory Integrity

Cannot Turn On Core Isolation Memory Integrity in Settings

core isolation was on for me without me doing a thing i think and i use kis. is vt-d and stuff enabled in your bios?
i do notice that i cannot scan a selected file with defender from right click context menu. it tells me something about it admin limiting access.

i didn't turn on memory integrity as i'm not sure what it does and i read here that you can't turn it off without going into registry

and somehow the firewall part says kis is handling the firewall, but under win def firewall bit the toggle is set as on. in control panel it says win def firewall off kis firewall on though. so i'll leave it as is

my mistake, maybe. i thought core isolation and the memory integrity are 2 separate things and that core isolation was on, since the gfx next to the words "core isolation" has a green tick on it and there's text saying "virtualisation-based security is running to protect the core parts of your device". too chicken still to touch memory integrity.
