@Dark Dinosaur you are a genius sir

 

That's exactly the whole point of modding a crappy OS like W11, making it working NOT as intended (by MS), but as desired (by the user), fanboys should realize that simple fact, sooner or later.

 

I have completely disabled Windows Defender and all of its services but there are some updates that were installed prior to me disabling it that show up in the Windows update history.

If I try to uninstall these updates using "wusa.exe /uninstall /kb:<kb number>" it says the updates is not installed yet it still shows in the history.

I want to clear that section completely

 

You need remove packages from Component Based Servicing but I no warranty for stable os. First test on VM prepare OS and then live test.

 

I have Windows Defender removed but when there is an update if you do not have Windows Update just download it installs Defender again when you install Windows Malicious Software Removal Tool or Windows Security platform antimalware platform update, the way I I found so that it does not do it is to put Windows Update that only downloads, does not update and before installing anything, hide the updates that I do not want with the Show or hide Updates program (wushowhide) and before updating after hiding those updates in Windows Update, give to pause updates and then search and those do not have to appear if you have hidden them well and do not install them

Hi everyone. After several years of operation, an automatic tool that disables Windows 11 defender no longer works. The problem is that by doing numerous installation tests, many exe files are blocked or deleted and therefore I need to block defender again. Could you recommend an app or a script to disable it for subsequent reboots? If this is no longer possible, would you recommend an alternative antivirus to take its place and which is easier to disable when I need to? Thank you

Open regedit as Administrator, set these values, then restart.

Code:

HKLM\Software\Microsoft\Windows Defender: [DisableAntiSpyware] = 1

HKLM\Software\Microsoft\Windows Defender: [DisableAntiVirus] = 1

HKLM\Software\Microsoft\Windows Defender\Features: [TamperProtection] = 0

HKLM\Software\Microsoft\Windows Defender\Real-Time Protection: [DisableRealtimeMonitoring] = 1

HKLM\Software\Policies\Microsoft\Windows Defender: [DisableAntiSpyware] = 1

HKLM\Software\Policies\Microsoft\Windows Defender: [DisableAntiVirus] = 1

I prefer manual scanner than real time antivirus (KVRT/Kaspersky Virus Removal Tool is my favorite). IMO good firewall and browser extensions are more important.

 

Hey man I have been using these powershell commands and it is %100 solving my problem. I gave up on defender long time ago when it somehow recognizing intel and xerox drivers as virus. So I called it on Defender.

First, boot your computer into safe mode, and copy these into powershell (run as admin too)
$regpath='HKLM:\SYSTEM\CurrentControlSet\Services'
Set-ItemProperty -Path ($regpath+"\WinDefend") -Name Start -Value 4
Set-ItemProperty -Path ($regpath+"\Sense") -Name Start -Value 4
Set-ItemProperty -Path ($regpath+"\WdFilter") -Name Start -Value 4
Set-ItemProperty -Path ($regpath+"\WdNisDrv") -Name Start -Value 4
Set-ItemProperty -Path ($regpath+"\WdNisSvc”) -Name Start -Value 4
Set-ItemProperty -Path ($regpath+"\WdBoot") -Name Start -Value 4

Then, reboot to normal and run powershell as admin again then copy these;
Get-ScheduledTask “Windows Defender Cache Maintenance” | Disable-ScheduledTask
Get-ScheduledTask “Windows Defender Cleanup” | Disable-ScheduledTask
Get-ScheduledTask “Windows Defender Scheduled Scan” | Disable-ScheduledTask
Get-ScheduledTask “Windows Defender Verification” | Disable-ScheduledTask

Use it at your own risk. It completely disables realtime protection and scans. Hope it helps

Edit: typos.

Hello, As of today you can completely disable windows defender in the latest official build of windows 11 without corrupting the system and you stop working preinstalled applications such as notepad, snipping tool and so on? .... I do not mean disable the defender from the toogle (which then stays the service "antimalware service executable" also running in the background), if not remove and disable it completely (background process included) without corrupting the OS.

I had the same problem a couple of months ago, that's why I'm asking if after this time you can finally do it.

Best regards

 

What is the specific build? What steps did you take?
Please provide more details

 

Hi. Compilation 22621.2134. Steps?, all the scripts that I tried at the time and that were recommended to me by the forum:

- Control Defender Switch 2.01
- Defender control 2.1
- Remove Defender 4.0

All of them were the same. I disabled windows defender yes, but in return the system was somewhat corrupted and some preset applications stopped working (notepad, clipping tool, the XBOX application took too long to start the gamepass games, etc ...).

Basically that. Best regards
