Why is Defender Firewall still in Control Panel in Windows 11?

Thought I had it figured out: Windows Security replaces Defender in Windows 11. In fact, Defender was lurking in my system tray and causing problems, and now that I've removed it, Security works better.

But why, then, is there still a Windows Defender Firewall in my Control Panel? And how do I get rid of it? (Assuming the Firewall in Security is something different.)

Welcome to Eleven Forum.

It's exacly the same Windows Firewall whether you get to its settings in Windows Security or through the Control Panel. For example, try clicking 'Allow an app through Firewall...' in either, you'll end up at the same place - a Control Panel page.

Microsoft are slowly migrating functions from Control Panel into the Settings app. But they will only remove it from Control Panel once all settings are available in the Settings app. For the Firewall that's not true (yet).

So no, you don't want to remove Firewall from Control Panel, there are still a few things that can only be set from the Control Panel.

Also, many things in Windows 11 settings may still show as Windows 10 so as mentioned the full migration has not been completed.

Thanks, that's very helpful!

Yeah, I noticed that, it's a weird hybrid.

How did you remove Windows Defender, what method did you use?
Does it start if you try opening it via Control Panel?
I searched for Defender in the Start Menu and found both the Windows Defender Firewall control panel, which I didn't touch, and a Defender app, which I right-clicked and removed, and no longer shows up. The Windows Defender Firewall item in Control Panel still starts.

I actually don’t know what that removes.

You don’t need to remove it, just disable it. I personally would advise against removing it. It can be done apparently with a little research, but I would’t research it for you because I believe it could be detrimental to your PC..

It looked like the old Defender app. Removal was easy and painless. After removal, Security remained fully functional. Only change to my system is that there no longer is a separate Defender app, and it no longer has a separate icon in the systray. Also, I have some hopes that the issue I was experiencing with Security/Defender is gone: quite often, neither were responding when I tried to open them from the systray, and now, Security always opens, it seems.
