Fix Windows Security on Windows 11 Beta

Technology Sep 22, 2021

In the Windows 11 Beta, I experienced an issue with Windows Security (fka. Windows Defender) not working.

The shield would appear in the system tray but clicking on it or opening Windows Security from the Start menu wouldn't do anything.

To fix this, open Powershell as Admin and copy paste the following:

Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage

Once you do that, you can go to: Start -> Settings >> Privacy & Security and click on "Open Windows Security" or type "Windows Security" into the Start Menu.
