An introduction to the basics of using  your Windows PC. How to use the keyboard, mouse, desktop, My Documents,  files and Control Panel.  
 
 The Mouse
The 
Mouse is the device you will use for most of your  interactions with your PC. It is primarily used to move the pointer  arrow around the screen and to select and activate options.
The mouse buttons are used to interact with whatever is on the screen  where the pointer is located. The left mouse button is the one you will  use most often. Clicking this tells the PC to select an item and is  called 'left-clicking'. To activate an item and use it, you will often  need to click the button twice or 'double-click'.
If you click and hold the left button and move the mouse, this has the  effect of 'dragging' a selected object about the screen until you  release the button.
Left-clicking on text in a document will place a flashing cursor at that point, which allows you to begin typing there.
The right mouse button is usually used to bring up a small menu window  that gives options specific to the selected object. To use a particular  option you just left-click it.
Common right-click menu options for an object include: 
Open (activate, same as if you double-click), 
Cut (remove to be placed elsewhere), 
Copy (make a copy of this object) , 
Create Shortcut (create a shortcut link elsewhere to give quick access to this object), 
Delete (remove permanently), 
Rename (give a new name), and 
Properties (find out information).
You may have a third smaller button in the center of your mouse that can  be rolled forwards and backwards. This mouse-wheel can be used to move  up and down through documents.
 The Keyboard
Keyboards can come in a number of different layouts. QWERTY keyboards are so-called because the top line of letters, underneath the 
number line, begins with those six letters.
There are a number of other useful keys too. The 
Enter key confirms a selection, and 
pressing the 
Shift or 
Caps Lock keys activates uppercase letters when you type, or 
special characters on number keys.
There are a number of function keys beginning with 
F1, 
F2 and so on, and these are used to access different options in different programs. Other keys such as 
Home, 
End and 
Page Up and 
Page Down allow you to quickly move about within a document.
The arrow keys move the text typing cursor up, down, left or right.
You may have a number keypad too. This acts as an alternative to the number keys above the main letter keys. Pressing the 
Num Lock button will switch between using the keypad as number keys, or arrow keys.
There are certain key combinations that can be used to perform particular tasks. See 
Keyboard Shortcuts for 
more information.
 The Desktop
The 
Desktop is the main background on your screen when you are working on your PC. It consists of a background 
picture or 'wallpaper', any 
program shortcuts you have created, and the 
Taskbar.
The Taskbar runs along the bottom of the screen (or the side, or top -  you can click and drag it wherever you want to place it) and shows 
the date and time as well as giving you access to the 
Start menu. You can also put program shortcuts on the taskbar so that one click will activate a particular program.
Left-clicking on the 
Start menu brings up the 
All Programs  list of shortcuts to programs you have on your computer. These are  often arranged in 'folders', so that you can find all the programs made  by one company under a folder in their name.
By holding the mouse pointer over a folder you will see a new list  appear of whatever programs are within that folder. Some programs will  have several related entries - so you might see a README (a document  that has instructions for using the program), or an option to 
Uninstall (remove the program from your PC).
You can access your Desktop settings by right-clicking anywhere on the background wallpaper and then clicking on 
Properties.
 Windows
The operating system that runs all your programs and allows you to easily interact with your PC is called 
Windows  for a good reason. It allows you to work with several different items  and programs at once, all in their own 'window'. A window is like a  smaller screen contained within a box on your main screen.
When you are working with a window it is brought to the 'front' of the  screen, overlapping the Desktop and any other items behind it, so that  you can focus on whatever is in the window.
In this way, you can have several windows open at the same time  containing different programs that can be opened, closed, and  re-arranged across the screen. This means you can do multiple tasks at  the same time, such as playing your favorite music while writing an  e-mail for example.
 Files And Folders
Every item stored on your PC, whether it is a document, picture, song, game or whatever, is a 
file. A file can only be activated by programs that 
understand and are able to use it.
For example, you cannot use a 
music program to open a letter document. Each program on your computer understands what type of file it can or cannot use by the fact that every file has a 
filetype given to it.
This takes the form of a few extra letters or numbers 
added  on to its name after a full stop. So for example, 'myletter.doc' is a  file named 'myletter' with the filetype '.doc', meaning it will require a  program that understands doc (document) files, such as 
Microsoft Word.
There are many different filetypes. Read 
Common Filetypes for a list of the more common.
Any one single program or application can actually consist of many different files, all working together to achieve the same task.
This means modern computers can have millions of files spread across different locations. 
Folders help 
organize these files, so that for each particular program there can be one folder that contains all the files it needs in one place.
A folder can even contain other folders inside it called 'sub-folders'. For example, to organize  your holiday pictures together you might have a folder called 'Holidays  2006' and then other sub-folders within that for each particular  holiday destination, for example 'France 2006'.
You can create your own folders. You can also create shortcuts to make it easier to find particular files. Read 
Organize Your Files/Folders/Shortcuts to learn more.
You can take a look at an example of a folder now. On your Desktop you should see a shortcut icon called 
My Documents. Double-clicking this will open a new window showing the contents of the 
My Documents folder.
 My Documents
My Documents is a folder on your computer that is automatically created  for you, so that you can store all your own files in one place away from  all the program and system folders, making them easier to find.
Double-click the 
My Documents shortcut on the Desktop and you  will see a list of folders, within which are your files. To see what is  inside a folder, double-click on it and the current window will change  to show the contents.
You may see some other folders which have been automatically created for you to help you store certain types of files, such as 
My Music, 
My Pictures and 
My Videos.  However, you do not have to use these, and you can store any of your  files in any folder you want to. You don't even have to use My  Documents, though it is usually easier if you do.
 My Computer
Close any open windows by clicking the 
X button in the top-right. On your Desktop, double-click the 
My Computer shortcut and you will see a list of locations where files are stored on your PC's disk drives.
If you double-click the 
Local Disk (your Hard Disk, usually 
C:  ) you can see all the folders that are stored on your Hard Disk - this  will be the part of your PC where all your files are usually kept,  unless you have extra disk drives.
The 
Program Files and 
Windows folders here are especially  important, and should usually not be changed as they contain the files  necessary for programs and Windows to run.
All files take up 'disk space' and your computer only has so much room  to store them all. If you want to see how much of your Hard Disk you  have used up so far, and how much space you have left, double-click 
My Computer again and this time, instead of double-clicking the 
Local Disk, right-click it and select 
Properties.
If you find you are running out of disk space, you should try to clean up some unnecessary files. Read 
Clean Out And Clean Up Files for more information.
If you decide you need a lot more space than you have, it is possible to  buy extra Hard Drives and connect them to your computer.
If you right-click the My Computer icon on the Desktop rather than double-clicking it, and then click on 
Properties, you can see detailed information about your PC including your hardware devices and performance settings.
 The Control Panel
The 
Control Panel is a collection of all the important options  you will need when you want to change settings on your computer. You can  find control icons for display, sound, Internet, hardware, programs,  security and system settings. To access the Control Panel, click the 
Start menu and then click 
Control Panel.
Changing settings in the Control Panel can make big changes to your PC's setup. For example, the 
Appearance and Themes or 
Display options in the Control Panel can affect the quality of your screen and the size of text. Read 
Change Display Settings And Text Size for more information.
