Under Windows 2000 you access the applications you want to use, and create and manipulate files directly from the desktop. Windows 2000 refers to directories as Folders and their contents as Files. A folder may contain other folders.
The following is a brief explanation of each of the items labelled in the illustration above. You will become more familiar with them as you use them.
The Title Bar shows the name of the application or of the document you have opened. If you have more than one window open, the title bar of the active window will be of a different colour or intensity from the others.
The Window Title depends on the type of window. It usually shows the name of the application and the name of the file you are working on.
The Menu Bar lists the available menus.
Most applications have a File menu, an Edit menu and a Help menu, as well as menu options unique to themselves. Some windows also have a Tool Bar, which enables you to access frequently used menu options easily.
Scroll Bars allow you to move around and view other parts of a document or a list when the display is too big to fit into the window area. Instructions for using these are below.
Maximise 
and Minimize 
buttons
(chosen with the mouse) enlarge the active window to fill the entire desktop or
reduce the window to an icon on the Task
Bar. By default, windows open to
occupy only part of the screen. When a
window is enlarged to full size, the Maximise
button changes to the Restore 
button and clicking on it reduces the size of the window.
The Close Button 
will close down the current application, this
can also be done by selecting the File
menu and Exit.
The Window Border is the outside edge of the window. You can use both this and the Window Corner to change the size of a window. This is covered in the next section.
The Status bar keeps you informed of the applications current status, such as when it’s saving a file or printing or repaginating a document.
