Whenever I do an Autoupdate, there are often slight changes to the system tray icons. Or, they are in a slightly different order.
Today, WU gave me an update for the display adapter; afterwards, my networking icon disappeared! (But I was still connected okay.) I went to the properties for Notification Area (Taskbar and Start Menu Properties) and the Networking checkbox was unchecked. I checked it. I've also had times when the Networking checkbox was completely grayed so I couldn't check or uncheck it.
