Hi, Dave.
If you really mean the Quick Launch toolbar, then just drag'n'drop the icons
into the order you like. You may need to Unlock the Taskbar first
(right-click in the Taskbar area to start).
If you mean the Notification Area near the clock (which many of us still
call the System Tray, or SysTray) the answer is more complicated -
basically, no, we can control whether they appear, but not the order.
Right-click the clock and choose Customize Notifications... to see what is
possible here.
