HOW TO REINSTALL WINDOWS DEFENDER ON WINDOWS 11

You cannot reinstall Windows Defender (also known as Microsoft Defender) like you do regular software since it is not installed on your computer in the same way as other programs. Instead, utilize a PowerShell command to complete the task by following these instructions. After completing these steps, there is an easier method if you can open Settings regularly.

  1. Right-click the Start button and select Windows Terminal (Admin).

    Note: If that doesn’t work for whatever reason, use the search bar on the taskbar to search for PowerShell, and then right-click it to find the Run as administrator option.

  2. Copy the command exactly as it’s shown here, then right-click in the PowerShell window to paste it (Ctrl+V works, too):

    Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage
  3. Press Enter to immediately start the process to reset Windows Defender to its original settings so that it performs as a freshly installed app.

  4. It’s finished when you see the blinking cursor again on a new line below the command you entered. In the meantime, you might briefly see a Deployment operation progress message.

    Note: If you see lots of red text, and an “Access is denied” message, return to step 1 and make sure you’re opening PowerShell as an administrator.
