In graphical computing, window decorations are provided by window managers to improve the usability of a multi-windowed desktop. They typically consist of a title bar along the top of each window and a minimal border around the other three sides, although this can often be varied upon if the user wishes. On Windows this is called "nonclient area".
In the predominant layout for modern window decorations, the top bar contains a title and buttons which perform windowing-related actions such as minimizing, maximizing and closing . The border exists primarily to allow the user to resize the window.
Window decorations are important in developing the look and feel of a desktop environment. However, modern systems allow for great customization of the colors, styles and animation effects used. User modifications some times cross between the appearance of different desktop environments.
