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

  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
