Windows 11's Windows Security App can't open.

Alright guys, just now I'm trying to disable the Windows defender but I found out that I can't even open the Windows Security App. Anyone knows what's going on? Any solution? I'm looking for help.  ...

    Hello,

    Suggest try the following steps:

    • Open PowerShell by using Administrator rights
    • Copy and paste Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage to the PowerShell window and press enter
    • Close the PowerShell and retry

MASA-0 I got the same error, so this is what I did:

Open PowerShell, type: Get-AppxPackage Microsoft.SecHealthUI -AllUsers
Type enter.

Open it again and type everything now: Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage

Type enter. 

 

Close PowerShell and try opening the Windows Security app. It worked for me! :smile:
