Clicking Start displays a menu that lets you easily access the most useful items on your computer. You can click Help and Support to learn how to use Windows, obtain troubleshooting information, receive support, and more. Clicking All Programs opens a list of programs currently installed on your computer.
The list of programs on the Start menu is divided into two parts: the programs displayed above the separator line (also known as the pinned items list) and the programs displayed below the separator line (also known as the most frequently used programs list). The programs on the pinned items list remain there and are always available for you to click to start them. You can add programs to the pinned items list. XOX
Programs are added to the most frequently used programs list when you use them. Windows has a default number of programs that are displayed on the most frequently used programs list. When that number of programs is reached, the programs you have not opened recently are replaced by the programs you used last. You can change the default number of programs displayed on the most frequently used programs list. XOX
You can customize the Start menu by adding a folder called My Recent Documents that contains the files you opened most recently. Another way you can customize the Start menu is to set items to open when you pause on them with the mouse, a simpler way to view the contents of the item.
