Quick answer
Distinguish tray visibility from application status. A missing tray icon can be hidden in overflow, disabled in configuration, or absent because the application is not running. Check those possibilities before resetting the taskbar or reinstalling StartAllBack.
What matters for this task
The notification area contains different kinds of items: operating-system controls, third-party application icons, and temporary status indicators. A problem with one audio or network flyout is not the same as every tray icon disappearing.
Steps to follow
- Open the tray overflow and check whether the supposedly missing icon is there.
- Confirm the related application is running and that its own option to display a notification icon is enabled.
- Compare the active Windows and StartAllBack tray settings. Change only the setting relevant to the affected icon or flyout.
- Test clicking, right-clicking, and returning from sleep. Record whether the failure affects system icons, app icons, or both.
Verify the result
Visible icons should open the expected controls and remain usable after a session change. An icon being present does not prove its associated app is healthy.
Limits and rollback
Restore the previous tray layout or disable the customized component while investigating. Avoid deleting icon-cache files before identifying the narrower failure.
Questions about this task
Does a hidden tray icon mean the app stopped?
No. Check the overflow and application state separately.
Should I reset the entire taskbar for one bad flyout?
Start with the affected control, its app, and the relevant release notes before making broader changes.
