Disable Windows Defender in Windows 11

Question

How to disable Windows Defender in Windows 11 (Professional) (i.e. prevent Antimaleware Service Executable to spin up my (completely disconnected) Laptop's fans)?

The top answer of Disable Windows Defender in Windows 10 recommends to set Turn off Windows Defender = Enabled in Computer Configuration > Administrative Templates > Windows Components > Windows Defender with gpedit.msc. But said Configuration does not seem to exist in windows 11 (there is only "Windows Defender Smart Screen").

Answer 1

1. Disable Windows Defender scheduler tasks:

   Get-ScheduledTask | Where-Object { $_.TaskName -like "Windows Defender*" } | Disable-ScheduledTask
   

   
   
2. Boot to Safe Mode, then:

   msconfig
   Disable related Windows Defender services:
   foreach ($SVC in "Sense", "WdBoot", "WdFilter", "WdNisDrv", "WdNisSvc", "WinDefend") {
       Set-ItemProperty -Path ("HKLM:\SYSTEM\CurrentControlSet\Services" + $SVC) -Name Start -Value 4
     }
   

   
   
3. Reboot → Windows Defender service should be deactivated:

   msconfig
