Core Isolation can it work without Defender?

core isolation without defender can it work?
is it enough to just activate the security center without defender, because honestly the windows feature that makes it too heavy is defender and if there is a trick please teach me, thank you...

I do this because most of the windows roles are only used to play online games

The last time I disabled Defender services, I believe Core Isolation still worked in Security Center. When you have 3rd-party AV, Defender is normally disabled so Core Isolation cannot be tied to having Defender running at the time.

Defender will complain when you have CI turned off. But I don't think CI complains about Defender.

garlin as it is said brings further opportunities
I have read in the previous post that you said that the defender component can be removed until it no longer works, in Windows 11 the defender cannot be separated from Microsoft.SecHealthUI, the question is how to make the defender preinstall fail and only Microsoft.SecHealthUI is installed when installing Windows

You can disable Defender services in W11, and SecHealthUI will work. This allows you to have access to the Security Center, but not have Defender running in the background.

When I disabled Defender in one of the threads, I used Security Center to confirm the non-Defender settings (like Firewall) were available.
