How is the computer controlled using the menu?

Using the mouse, we click on Start and open the computer menu. The menu is a rectangular area that pops up at the bottom left of the working screen. Then the user clicks on the left mouse button and selects the desired menu item from the proposed options. Thus, it controls the computer, while selecting the necessary programs, documents, applications, and making adjustments to them. The menu displays all programs saved on the personal computer.
