Problem

KES System Tray icons display unexpected behavior:

• There is more than one KES icon;
• You do not see any icons at all, despite that Do not display user interface option is not enabled in KES policy.

Solution

Reset the tray icons:

1. Open Registry Editor. Press Win + R, type regedit, press Enter.

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 back up & delete the PastIconsStream Registry value.
5. Close Registry Editor.
6. Open Task Manager. Go to File → Run new task or Processes → Run new task depending on the OS version.
7. Type Explorer in the Create New Task dialog and press Enter to restore Desktop.

This should fix the 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.
