You can reset Windows Security using following command in Windows PowerShell:

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

Answer 2

1

Click your Start Button, then just type Powershell and on the resulting list, right click PowerShell and select 'Run as Administrator'.

Paste this command into Powershell and press Enter:

HKLM\SOFTWARE\Policies\Microsoft\Windows Defender" /f; Set-MpPreference -UILockdown 0

When that completes, paste this command into Powershell and press Enter:

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

When that completes, paste this command into Powershell and press Enter:

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

Close PowerShell and restart (not shut down) your PC, then check if WIndows Security can be opened successfully.
