I think that you can turn it off using Autoruns. See screenshot here:

How to Turn On or Off Microsoft Defender Antivirus in Windows 10

I disabled it but subsequently re-enabled it after reading somewhere that it should be left on even if using a third party firewall/ AV with Defender disabled/ removed.

Defender can be disabled using Winaero Tweaker, also. If Tamper Protection is on, you need to disable it first.

Ok guys. Let's start with this. Here is my Windows 10 version: Win 10 Home 10.0.19041.450 [2004]

As far as I can tell, I already have Windows Defender AV, shut off.

Now the problem is the Windows Defender Firewall. I can disable it, but as soon as I reboot, it turns itself back on.
This is because I can't disable the Windows Defender Firewall Service. It all greyed out.

Apparently this is because of the May 2020 Feature Update. None of the normal solutions work. I've been googling and reading tutorials about the Windows Defender Firewall for days, if not weeks.

I'm about to try Autoruns (the program). I doubt Microsoft over looked that, but we'll see.




/edit Ok, apparently... Windows Defender Firewall doesn't show up under Services, in Autoruns.






Oh, and here's what I see for Virus and Threat Protection... which I assume means the WD AV is OFF and Bitdefender has the con, so to speak.

These are verboten to alter, if it helps.

Autoruns - Options - uncheck Hide Windows entries or change startup via registry:

Code:

reg add "HKLM\System\CurrentControlSet\Services\mpssvc" /v "Start" /t REG_DWORD /d "4" /f

@Brink ...for adding to tutorials for Win 10 HOME (2004) folks??

Already did that. Further in the little filters box (top left) I typed in Windows defender and checked each tab.
There was the one you highlighted and.... this little nasty Windows Defender Firewall DRIVER.

Needless to say.. Windows Defender Firewall is disabled, and it's SERVICE is disabled as well.















...and this is AFTER a reboot.

I see I have some cookies to hand out.

Does this script apply to all editions of Windows 10 20H2?

If I install this script to permanently disable Windows Defender Firewall/Antivirus, will I have no side effects?

Thanks

Bye

After disabling Windows Defender with Autoruns (free), I saw no adverse effects at all.
This works on all versions of Windows 10.



Note: You have to set "Options" as shown here to get the same view I got in post # 14








THEN... you need to uncheck the boxes shown below. This will allow you to disable Windows Defender in "Services".

So, using this script, what would be the correct procedure to permanently disable Windows Defender Firewall/Antivirus on Windows 10 20H2?ThanksBye

Just use Defender Control v1.6 - it is one click solution, effective immediately (no restart).
I prefer to disable it completely by stopping services, but it is harder to get it back on.
