Open source windows defender disabler.
Now you can disable windows defender permanently!
Tested from Windows 10 20H2.
Also working on Windows 11

We all know that disabling windefender is very difficult since microsoft is constantly enforcing changes.
The first solution is to install an anti-virus - but thats not the point if we are trying to disable it!
The next easiest solution is to use freeware thats already available on the internet - but none of them are native & open source...
I like open source, so I made a safe to use open source defender control.

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.

1. It gains TrustedInstaller permissions
2. It will disable windefender services + smartscreen
3. It will disable anti-tamper protection
4. It will disable all relevant registries + 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.
