Show or hide icons in the taskbar
You can show or hide icons on the Quick Launch toolbar and the notification area (also called the system tray), on the far right of the taskbar.
Point to the Quick Launch toolbar sizing handle.
When the pointer turns into a double-headed arrow
click it, and then drag the toolbar sizing handle to show or hide more or less of the toolbar.
If you can't change the toolbar, it's either as small as it gets, or there's not enough room on the taskbar to show more of it.
