The Registry path in this posting did not work for me. So I searched the Registry for "TrayNotify" and found it in the following path: HKEY_CURRENT_USER\Software\ Microsoft\Windows\CurrentVersion\explorer\TrayNotify. I had to lock the Taskbar because my computer reverted back to not showing the complete System Tray Icon collection when rebooted. I hope this helps. No offense against the original poster intended!
