Open-source Windows Defender disabler.
Now you can disable Windows Defender permanently!
Tested from Windows 10 20H2.
We all know that disabling WinDefend is very difficult since Microsoft is constantly enforcing changes.
The first solution is to install an anti-virus - but that's not the point if we are trying to disable it!
I like open-source, so I made a safe-to-use open-source Defender controller.
Sometimes Windows decides to update and turn itself back on.
A common issue is that Defender Control sometimes doesn't want to disable tamper protection again.
Please try turning off tamper protection manually then running disable-defender.exe again before posting an issue.
- It gains
TrustedInstallerpermissions / privileges - It will disable WinDefender services + SmartScreen
- It will disable anti-tamper protection
- It will disable all relevant Registry keys + WMI settings
Yes it is safe, feel free to review the code in the repository yourself.
Anti-virus & other programs might flag this as malicious since it disables Defender - but feel free to compile it using Visual Studio.
Open the project using Visual Studio 2022 Preview.
Set the build to Release and x64.
Change the build type you want in settings.hpp.
Compile.
You can find the first release over at the releases on the right.

Works for earlier versions of Windows 11. Correct registries have not been added yet for the latest version.
Update, TrustedInstaller no longer has effect on the current live versions of Windows 11. Use with caution.
