I'm using Windows 10. I have been using Windows Security from first. I once installed a third-party anti-virus. And uninstalled it the same day. But, the Windows security was working perfectly fine. But, the next day, the security app is not opening and shows some clues that the application is uninstalled.

    Hi,

    Please open the Microsoft.SecHealthUI directory under C:\Program Files\WindowsApps and see if the AppxManifest.xml is still there. If yes, open Windows PowerShell as administrator and reinstall the appx package by running

    Add-AppxPackage -register <full path of appxmanifest.xml> -DisableDevelopmentMode

    If it does not work, give a try to the commands

    DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

    and

    SFC /scannow

    Best Regards,

    Ian Xue
