App icons not appearing on taskbar while apps are active

Question

I need assistance with an issue on my Windows device. Most application icons are not appearing on the taskbar while the apps are open and active.

Can I please advise on what may be causing this and how I can restore the app icons to display properly on the taskbar?

Thank you.

Answer 1

I am having the exact same issue, the difference being I am experiencing this system-wide...

Yes, for some reason I have duplicated no icon default app suggestions.

Idk if its the recent update or what but its is very annoying to work with & reinstalling windows changed nothing. Any other solution?

Click the Start button, type cmd, and in the resulting list, right-click Command Prompt and select 'Run as administrator'.

Run this command and press Enter:

taskkill /f /im explorer.exe

Run this command and press Enter:

del /a /q "%localappdata%\IconCache.db"

Run this command and press Enter:

start explorer.exe

When the command completes, close Command Prompt and restart (not shut down) your PC.

If that process does not resolve the problem.

Open the Settings App, go to System - Recovery.

Click the 'Reinstall Now' button in the 'Fix problems with Windows Updates' section and wait for that process to complete, this process will not affect your files, settings or installed apps.

Several different issues can cause taskbar icons to disappear or show as blank while apps are running. Use these steps in order, testing after each section.

1. Check taskbar icon visibility settings

In Windows 11, some icons may simply be hidden:

1. Go to Start > Settings > Personalization > Taskbar.
2. Under Taskbar items, make sure the items that should appear (for example, app icons, search, Task view, Widgets) are enabled as needed.
3. Expand System tray icons and Other system tray icons and turn on the toggles for apps that should be visible.
4. Under Taskbar behaviors, make sure Automatically hide the taskbar is turned off while troubleshooting.

This ensures icons are not just hidden or minimized to the overflow area.

2. Clear and rebuild the icon cache

Corruption in the icon cache can cause blank or missing icons on the taskbar, Start menu, and desktop.

1. Open Task Manager (Ctrl+Shift+Esc or right-click the taskbar and select Task Manager).
2. On the Processes tab, find Windows Explorer, right-click it, and select End task.
3. In Task Manager, select File > Run new task.
4. Type cmd.exe, check the option to run with administrative privileges, and press Enter.
5. In the Command Prompt window, run:

      CD /d %userprofile%\AppData\Local
      DEL IconCache.db /a
   

6. Back in Task Manager, select File > Run new task again.
7. Type explorer.exe and press Enter to restart Windows Explorer.

This forces Windows to rebuild the icon cache and often restores missing/blank icons.

3. Re-register Shell Experience Host

If the Shell Experience Host is not correctly registered, taskbar and shell UI elements (including icons) can behave incorrectly.

1. Open Windows PowerShell as administrator.
2. Run:

      Get-AppXPackage -AllUsers | Where-Object {$_.InstallLocation -like "*ShellExperienceHost*"} | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
   

3. Restart the device.

This re-registers the Shell Experience Host for all users and can fix taskbar icon display issues.

4. Verify the IconHandler registry configuration (advanced)

If icons for shortcuts (.lnk files) are blank or missing, the IconHandler registration may be damaged.

Editing the registry incorrectly can cause system problems. Back up the registry first. For guidance, see How to back up and restore the registry in Windows.

1. Open Registry Editor (regedit).
2. Navigate to: HKEY_CLASSES_ROOT\lnkfile\shellex\IconHandler and check the (Default) value. In the documented example it is: {00021401-0000-0000-C000-000000000046}
3. Navigate to: HKEY_CLASSES_ROOT\CLSID\{00021401-0000-0000-C000-000000000046} and confirm the (Default) value is Shortcut.
4. Navigate to: HKEY_CLASSES_ROOT\CLSID\{00021401-0000-0000-C000-000000000046}\InProcServer32 and confirm the (Default) value is: C:\Windows\System32\windows.storage.dll

If these values differ, correcting them to the documented values (after backup) can restore proper shortcut icon handling.

5. Check for policies hiding the notification area (if system icons are missing)

If system icons (network, volume, etc.) are missing from the taskbar, a policy might be hiding the notification area:

• In Group Policy, check: User Configuration > Administrative Templates > Start Menu and Taskbar > Hide the notification area.
• Disable this policy if it is enabled.

For local policy editing, see the guidance in How to disable user or computer policy settings in a Local Group Policy Object.

If, after these steps, icons are still missing while apps are active, the issue is likely deeper shell or system corruption and may require in-place repair or reset, but the steps above cover the documented causes related to icon cache, Shell Experience Host, taskbar configuration, and icon handling.
