The McAfee system tray icon is missing after logging on to Windows.

The tray icon for McAfee products is created by the process McTray.exe. McTray.exe is a child process, invoked by the process UpdaterUI.exe. UpdaterUI.exe is invoked when the user logs on to the system because there is the following Run key entry:

"McAfeeUpdaterUI"=""C:\Program Files\McAfee\Agent\x86\UpdaterUI.exe" /StartedFromRunKey"


The shortcut from the Run key has been removed (or was not installed).


Create the Run key entry:
