Group Policy

To complete the action, you need to turn off Tamper Protection first. Available since May 2019, this feature safeguards your system from unauthorized changes. To stress, the Defender will turn back on after a restart if you don’t disable Tamper Protection.

In the following window, go to Tamper Protection and click on the button to toggle it off. Now, you can access Group Policy to disable the native anti-virus altogether.

To enable the anti-virus, retrace your steps as previously described. But now, you need to select “Not Configured” instead of “Enabled.” You also need to reactivate Tamper Protection and restart your PC for the changes to take effect.

Bonus Method

If you’re not running Windows 10 Pro, you might not be able to access the Local Group Policy Editor. However, you can use Windows Registry to remove Windows Defender permanently.

Once there, right-click Windows Defender (it’s a folder), choose New, then select DWORD (32-bit) Value.
