Defender Control

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

What is this project?

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.

On windows updates

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.

What does it do?

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

Is it safe?

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.
