Turn system icons on or off. This is a list of the basic Windows

system-tray icons that are supposed to appear. Here you can hide
them. If you don’t want the time eating up taskbar space, then, by
golly, you can hide it.

Tip

If your intention in visiting the “Select which icons appear on the taskbar” box (Figure 2-26,
bottom) is to turn on all system-tray icons—maybe to recreate the halcyon days of Windows XP
—you can save yourself some time. Just turn on “Always show all icons in the notification area.”

Now all the icons appear in the system tray, and the button in the system tray goes away.
