The Start button is at the bottom of the screen, at the left-hand end of the Task Bar.
Click on it with the left
mouse button to display the menu choices available.
Move the mouse up the menu (there is no need
to hold the mouse button down), and you will see each option (an icon with a
description beside it) highlighted in turn.
Some options have an arrow beside them: as you move the mouse over these, sub-menus are displayed and these may also have sub-menus. Clicking once with the left mouse button on any menu item will open the application or folder it describes. The illustration below shows the screen with the Start Menu and several sub-menus expanded.
