Problem

Sometimes the KES tray icon behaves unexpectedly: it appears twice or does not appear at all (the icon next to the Windows clock).

Solution

Reset the tray icons:

1. Open regedit;

2. Go to HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify;

3. In the right pane, backup & delete the IconStreams Registry value;
4. Now backup & delete the PastIconsStream Registry value;
5. Close Registry Editor;
6. Open Task Manager Use File -> Run new task menu item in Task Manager;
7. Type Explorer in the "Create New Task" dialog and press Enter to restore Desktop.

This should fix tray icons issues. The Registry values above represent the notification area icon cache which stores the tray icons for all apps.

If this cache is corrupted, it may also prevent system icons from appearing in the tray.
