To move the taskbar from its default position along the bottom edge of the
screen to any of the other three edges of the screen:
Click a blank portion of the taskbar.
Hold down the left mouse button, and then drag the mouse pointer to the
place on the screen where you want the taskbar. For example, you may want
the taskbar to be positioned vertically on the right side of your screen.
After you move the mouse pointer to the position on your screen where you
want the taskbar, release the mouse button.
NOTE: The taskbar can be docked on the left side, right side, top, or
bottom of your screen. You cannot move the Start button from side to side
on the taskbar.
