The Start menu appeared automatically the first time you ran Windows XP. You can return to the Start menu anytime by clicking the Start button on the taskbar.
The Start menu contains everything you need to begin using Windows. From it you can:
Start programs.
Open files.
Customize your system with Control Panel.
Get help by clicking Help and Support.
Search for items on your computer or the Internet by clicking Search.
And more!
Some commands on the Start menu have a right-facing arrow, which means additional choices are available on a secondary menu. Place your pointer over an item with an arrow and another menu appears.
The left side of the Start menu updates with links to the programs you use most frequently. At the top left are fixed or "pinned" items—shortcuts to things like your Internet browser and e-mail program.
