Windows. Learn
the Basics.

Windows
is a program that makes it easy for you to tell your personal computer what to
do. Instead of memorizing commands and typing them at a prompt, you tell the
computer what to do by selecting buttons, pictures (called “icons”), and
commands from menus. Most of the time, you use your computer’s mouse to make
the selections; choosing a command is as easy as pointing to an option and
clicking a button on the mouse. Windows is designed to be easy to learn and
easy to use. With Windows, you can run more than one application at a time.
Each application you run, such as Word, Excel, or Netscape, appears in a
separate window, as if you had several computer screens but just one monitor.
By learning to manage the different windows, you can easily work on several
different projects at the same time. One major feature of Windows is its
flexibility. You can do a task in several different ways.

When you turn on a computer with Windows installed, you
first see a screen called the Desktop. Each window you open sits on this
desktop. The desktop is just like your own desk: you can keep it as orderly or
as messy as you like. On the
Desktop, you will see several icons, which are small pictures that are graphic
representations of computer files, devices or programs. You can customize your
desktop by right clicking on any blank area and choosing Properties. The Properties window gives you information
about the desktop and allows you to make changes to it. You will see various
tabs on the top of the screen in the Properties window.

Windows
does give you a tool that makes it easier to keep things tidy as you move from
task to task: the Taskbar, located at the bottom of
the window. At the far left side of the Taskbar is the button for the Start menu. The Start menu is the place you generally go to
start any program. You can also shut down your computer from this menu.

The programs or tasks that you
are running are shown in the small rectangles near the middle of the task bar.
Near the right side, you will see the programs or tasks that have been started
automatically when you started Windows. On the far right, you will usually see the time
displayed.

Depending on
how you have arranged your desktop, you usually see several icons on the left
side of the screen.     You can use My Computer to manage files and folders on your hard drive
(usually C:\) and any other drives to which you have access, such as a CD-ROM
drive, floppy disk drive (A:\), or your Local Area Network (LAN) server.

The Recycle Bin is where you discard files. Additional icons on your
desktop may provide access to files and shortcuts (shortcuts are icons that
have a small white arrow in the low left corner to point to a program, folder
or other item) to programs you frequently use.

Every
window has a Title Bar at the top. The Title Bar
has the name of the program and the name of the file. This is important
information, not to be overlooked. The Title Bar also has three small icons in
the upper right corner, that allows you minimize a window (make it smaller),
maximize a window (make it larger) or close a window. The menus at the top of
the screen are called drop down menus. When you click on any of the words in the menu a list of choices drops
down.

There is
often one or more toolbars under the menu choices. A toolbar is a row of icons.
These icons are shortcuts for choices that are in the menus. You can perform
most functions more quickly by using the icons on the toolbar. You display or
hide the toolbars by finding the Toolbar menu,
most often found in the View menu.

Scrollbars are
used to display the contents of a window that extend beyond the window’s
current viewing area. A scrollbar is a gray rectangle with small black arrows
on both ends. It can be seen on the left side and/or bottom of a window. You
can click on the arrows to make the screen move up and down or side to side.

When you
open (double click) My Computer, you will see an icon for the Control Panel. When you open the Control Panel, you will find
yourself in the area where you can control the Windows environment.
