Since the window parts of many of the window based application software are common, this makes a person to understand and memories faster. You will see that the button to maximize or to minimize always appear on the right top corner in all the windows. Similarly the menu bar, the title bar, the control menu bar also appears at the same place for all the windows. This way if you get familiar to one window, you will get familiar with the other windows too as the meaning for each of the similar buttons remains the same. Depending upon the type of application all windows, however, may not have every element.
