Right-click on an empty section of the taskbar and make
sure that there is no checkmark beside "Lock the
Taskbar". You should now see little vertical bars around
the quicklaunch. Hold down the left mouse button
and "drag" the quicklaunch to the same row as the start
button. The taskbar should contract to one row. You can
also drag the quicklaunch left and right as you please.
Once you like the way the taskbar looks, right click
again, and select "Lock the Taskbar". This will prevent
you from moving things around by mistake.
Hope this helps,
