    If Windows Defender is not working on your Windows 10 Pro, you can follow these troubleshooting steps:

    1. Restart Your Computer: Close all applications and restart your computer.
    2. Check the Windows Service:
      • Open services.msc from the Start menu.
      • Locate the Windows Defender Antivirus Service.
      • Ensure the Startup Type is set to Automatic.
      • If the service is stopped, right-click and select Start. If the option is unavailable, select Stop, wait for it to stop, and then select Start again.
    3. Remove Third-Party Security Programs:
      • Go to appwiz.cpl from the Start menu and uninstall any third-party security programs.
      • Restart your computer afterward.
      • Note that removing security programs may leave your computer unprotected temporarily.
    4. Check Internet Connection: Ensure your computer is connected to the internet, as updates are necessary for Windows Defender to function properly.
    5. Reset Microsoft Defender Antivirus:
      • Open an elevated Command Prompt and run the following commands:
             DISM /Online /Cleanup-Image /RestoreHealth  
             sfc /scannow  
        
    6. Update Security Intelligence:
      • Run the command in an elevated Command Prompt to update the security definitions:
             for /f "delims=" %d in ('dir "%ProgramData%\Microsoft\Windows Defender\Platform" /ad /b /o:-n') do if not defined _done "%ProgramData%\Microsoft\Windows Defender\Platform\%d\MpCmdRun.exe" -SignatureUpdate -MMPC  
        
    7. Contact Microsoft Support: If the issue persists after trying the above steps, consider reaching out to Microsoft Support for further assistance.

    By following these steps, you should be able to resolve issues with Windows Defender not working on your Windows 10 Pro system.
