1. A section of the computer's display in a GUI that shows the program currently being used. For example, the browser window that you are using to view this web page is a window. Windows allow a user to work with multiple programs or view multiple programs at once. Almost all windows allow you to minimize and maximize them, allowing you to hide and view a program temporarily. Below is an example of what a window may look like in Microsoft Windows and each of its major functions, also known as the window elements.
Tip: If a window is not fullscreen (maximized), it is considered to be in window mode.
Basic features of the title bar
As illustrated in the above picture, the title bar typically has a minimize, maximize, and close button. In the top-left corner of a Microsoft Windows window is typically an icon of the program that can be clicked to also show these options.
Tip: In Microsoft Windows, pressing Alt + spacebar shows you the window menu options as shown in the picture. Using this keyboard shortcut allows you to perform any of the title bar options without having to use a mouse.
