This application removes / disables Windows Defender, including the Windows Security App, Windows Virtualization-Based Security (VBS), Windows SmartScreen, Windows Security Services, Windows Web-Threat Service, Windows File Virtualization (UAC), Microsoft Defender App Guard, Microsoft Driver Block List, System Mitigations and the Windows Defender page in the Settings App on Windows 10 or later.

If you have any problems when opening an app (extremely rare) and get the message "The app can not run because Device Guard" or "Windows Defender Application Guard Blocked this app", you have to remove 4 files with the same name, from different locations.

• In EFI Partition

Remove-Item -LiteralPath "$((Get-Partition | ? IsSystem).AccessPaths[0])Microsoft\Boot\WiSiPolicy.p7b"

• In Code Integrity Folder

Remove-Item -LiteralPath "$env:windir\System32\CodeIntegrity\WiSiPolicy.p7b"

• In Windows Folder

Remove-Item -LiteralPath "$env:windir\Boot\EFI\wisipolicy.p7b"

• In WinSxS Folder

Remove-Item -Path "$env:windir\WinSxS" -Include *winsipolicy.p7b* -Recurse

That is a false positive.

Some security apps flag this app as a virus because of the way the ".exe" files are created.

Windows Update includes a Intelligence Update which blocks certain actions and modifies Windows Defender/Security policies. If the script is not working for you, check if you have the Windows Security Intelligence Update installed. If you do, disable tamper protection, and re-run the script.

Run the desired ".bat" file from cmd with PowerRun (by dragging to the executable). You must reboot for the changes to take effect.
