[SOLVED] Windows Security doesn't open

Kross · Apr 9, 2022

Hi everybody,

I'm on Windows 11 Professionnel 21H2 since january and its been 2 months i don't have access to any windows security .
When I wanna open settings it looks like it needs a sofware to make it (pictures in attached file).

- In the Apps and Features list, there's no Windows Security.
- I don't have any antivirus software.
- I've tried "sfc/scannow" .
- I've tried "DISM /online /Cleanup-Image /ScanHealth".

Can someone help me

Thanks

Kross

Hi, Kross.

Try this:

In the Search area type PowerShell and select to run it as administrator (important).

Copy the following command and paste it in the PowerShell window.

Code:

Add-AppxPackage -Register –DisableDevelopmentMode "C:\Windows\SystemApps\Microsoft.Windows.SecHealthUI_cw5n1h2txyewy\AppXManifest.xml"

Enter.
Let the command to execute itself.
Restart the computer.
Check if you can open Windows Security.
