Before to start the script, an automatic system restore point is created. If something fails, can be restored easily.

🛑 Why is this downloaded app/script being flagged as a virus?

That is a false positive.

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

🛑 If i have a clean installed Windows with no updates the script is works, why in updated Windows the script is not working?

Updated Windows includes a Windows Intelligence Update this is designed for blocking actions , modifying Windows defender/Security Polocies, and so on. If the script is not work for you, first check if you have the Windows Security Intelligence Update installed. If you have, disable tamper protection, and re-apply the script.

📃 Automation of the script

OR

Defender.Remover.exe /r

Disable and/or Remove Windows Defender Application Guard Policies (deeper)

If you have some problems when opening an app (extremely rare) and it will be saying "The app can not run because Device Guard" or "Windows Defender Application Guard Blocked this app" you must remove 4 files (with the same name, from 4 different locations).

The location of the files are:

a. In EFI Partition

$Path_To_EFI_System_Partition\Microsoft\Boot\WiSiPolicy.p7b

b. In Code Integrity Location

$env:windir\System32\CodeIntegrity\WiSiPolicy.p7b

c. In Windows Folder

$env:windir\Boot\EFI\wisipolicy.p7b

d. In WinSxS Folder

This module is not added to the script because implementing the removal of the file from the EFI partition is impossible (for now) to implement.

Manually removal: Go to "C:\Windows\WinSxS" and Search for winsipolicy.p7b then delete the file.

i.e:

[IO.DirectoryInfo]::New("$env:windir\WinSxS").GetFiles("*", [IO.SearchOption]::AllDirectories).Where({ $_.Name -eq "winsipolicy.p7b" }) | Remove-Item -Force

Frequent questions

1️⃣. How to use the package remover without downloading the executable from the release?

RESPONSE: Run the desired ".bat" file from cmd with PowerRun (by dragging to the executable). You must reboot to take effect of the removal.

2️⃣. What are the ideal conditions for running the remover version of the script?

RESPONSE: The "ideal" condition is to run the Remover Version of the script on a Clean Installation of Windows. Why do I recommend that? Because the "Windows Intelligence Update" would not be installed and thus no defender package.
