Disable Windows Defender permanently with Registry Editor

Edit on GitHub

System Administration

tl;dr Open regedit as Administrator and add a bunch of hexadecmial values here: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

  1. Open regedit (Registry Editor) from the start menu. I did it as an Administrator just to make sure it works
  2. Go here: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender
  3. Right click on Windows Defender and add the following as DWORD (32-bit) Value
Value NameValue DataBase
DisableBehaviorMonitoring1Hexadecimal
DisableOnAccessProtection1Hexadecimal
DisableScanOnRealtimeEnable1Hexadecimal

You may have to add a value and then double-click it again to set it’s data.
