Left click and hold an empty spot of the taskbar and drag it to the bottom
of the screen.
The taskbar has several "components", The System Tray (aka The Notification
Area),
The Taskbar(displays buttons for running programs), and The Start Button.
When resizing the taskbar, you don't have fine control over its size, it
will snap to
sizes that are based on how many rows of icon buttons will be displayed.
If you open My Computer, you'll see an button on the taskbar for it, drag
the taskbar
to a smaller size, until it's just tall enough to show 1 button. vertically.
That's as small as it will go.
