        The most obvious window adoring you desktop are application window.these window contain a title bar that shows that program's homw,a menu  & perhaps a toolbar &scrollbar.less obvious are the various push buttons,radio buttons,check boxes,listboxes,scrollbar and text_entry filed that adorn that littel visual objects is a window.they called as "child window"or"control window"or"child window controls".
