Windows Basics: Getting Started with the Desktop Video Lecture | Basics of Computer and Internet (English) - Basic Technology

If you’re just getting started with Windows,
learning how to navigate the interface is
a great place to start.
Let’s take a look at the desktop, which
is the screen you see here. It includes a
desktop background, also known as your wallpaper,
and the Taskbar at the bottom of the screen.
The Taskbar is where you'll find shortcuts
to some of the applications on your computer,
as well as the Start button. In most versions
of Windows, you can click the Start Button
to see a list of applications, files, and
settings. But If you’re using Windows 8,
you can click the Start Button to return to
the Start Screen.
The Taskbar is also where you’ll find File
Explorer, which allows you to view and open
files and folders.
For now, I'm going to close the window by
clicking the X.
Let's check out more features on the Desktop
instead. The Desktop is the main workspace
for your computer. To open a program, file,
or folder, just double click the icon. Each
time you want to open something, it will appear
in a new window.
You have the ability to move windows by clicking
and dragging the top of the window. When you’re
done, just release the mouse.
If you have more than one window open at the
same time, you can quickly switch between
them by clicking the icon for that window
on the taskbar.
Almost all windows allow you to maximize the
window so that it fills the entire screen.
Just click the button here. Click the button
again to return the window to its original
size.
When you’re finished, closing the window
is easy. Just click the X.  
That covers the basics. Now that you know
your way around Windows, you can start taking
advantage of everything it has to offer.
