Instructions

How to disable Windows Defender

1. Disable Tamper Protection.
2. Run Disable.bat to disable Windows Defender.
3. Reboot.
4. Run it once (maybe more, thanks Microsoft) again so it can actually disable Windows Defender. Console output will say "SUCCESS" instead of "ERROR" when it actually disables it.
5. Once there's no "Antimalware Service Executable" in the Task Manager - it's disabled.
6. (Optional) Reboot once more, because sometimes Windows still manages to enable Defender by itself and you have to do everything from the start again.

How to enable Windows Defender

1. Run Enable.bat.
2. Reboot so that Windows can start services again.
3. Open Windows Security and check all the options (Real-time protection, Tamper Protection and etc.).
