    Hi and thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today.

    I understand the issue you have, nothing to worry I am here to help, I know some of these steps are already done, you have just skipped it if you think it will have the same result.

    Method 1. Repair Windows apps and Windows defender:

    On Powershell(admin), copy and paste the command below and hit enter:

    Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

    restart the PC and check

    Method 2. Reinstall Windows Defender

    Open registry, then go to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

    Then delete the Windows Defender folder, then restart the PC and check it again.

    Let me know how it goes and I hope that helps.

    Bernard

    Please make sure that there are no installed third party antivirus software.

    Open administrative command prompt and copy and paste:

    msdt.exe -id WindowsUpdateDiagnostic

    1. Start the Windows Security Service
    2. Start the Registry Editor (regedit.exe)
    3. Go to the following location: 
       HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SecurityHealthService
    4. Double-click "Start" and set its data to 3
    5. Exit the Registry Editor.
    6. Restart Windows.

    If that doesn't do the trick, then try a repair installation.

    It appears that the service has been deleted (by malware?). Pls check the 2nd link I posted to get the SecurityHealthCenter service registry file for Windows 10/11 (download). Run the registry file and restart Windows. This restores the Security Health Center service.
