Dear @azaraxi

  1. Check Settings --› Personalization --› Taskbar --› Other system tray icons and make sure Windows Security is enabled.
  2. You can also check Task Manager --› Startup apps for Windows Security notification icon. If it is disabled, enable it and restart the PC.
  3. If the icon is still missing, press Win + R and run: C:\Windows\System32\SecurityHealthSystray.exe

If the icon appears after running it, the Windows Security notification component is working, but it may not be starting automatically with Windows.

Best regards,
Bence

    Hi,

    If you can open Windows Security and everything looks fine, follow the steps in the Q&A; the Windows Security tray icon is likely disabled if the issue hasn't been resolved yet.

    Go to the Microsoft Store > Downloads > Get updates and wait for all apps to update.

    Restart your PC, then check if it worked by opening Task Manager, going to the Startup tab, and seeing if SecurityHealthSystray.exe is active.

    Thanks.

    If Microsoft Defender is still working, a missing taskbar icon does not by itself mean malware. A red status in Windows Security would indicate risk; green means protected, yellow means potentially unprotected, and red means at risk.

    Try these checks in order:

    1. Check the hidden tray area.
      • Select the up arrow on the right side of the taskbar.
      • If the Windows Security icon is there, drag it back to the taskbar.
    2. Make sure the notification icon is enabled.
      • Open Settings > Personalization > Taskbar.
      • Expand the system tray icons area and make sure the Windows Security notification icon is turned on.
    3. Check whether the Windows Security service is running.
      • Press Start, type services.msc, and open it.
      • Find Windows Defender Antivirus Service.
      • Make sure Startup type is Automatic.
      • If Start is available, select it. If not, select Stop, wait for it to stop, and then select Start.
      • If an error appears while starting the service, note the error.
    4. Restart the PC.
      • Close apps and restart Windows.
      • This is the first recommended step when the Defender service or notification behavior is abnormal.
    5. If another antivirus was installed before, remove it.
      • Open appwiz.cpl.
      • Uninstall any third-party security software.
      • Restart the PC.
      • Some security apps do not uninstall completely, so their cleanup utility might also be required.
      • Warning: removing security software can temporarily leave the PC unprotected.
    6. If the Defender service shows stopped or Windows Security shows errors, review Defender events.
      • Open Event Viewer.
      • Go to Applications and Services Logs > Microsoft > Windows > Windows Defender > Operational.
      • Look for events such as 5007 or 5001/5010, which indicate Defender configuration changes or real-time protection being disabled.

    If the service is running and protection status is green, the issue is likely only the tray icon display and not Defender itself being disabled.
