go to the folder that you have originally saved the word document in, right click and drag the file you want on to the desktop and you should see a shortcut appear for that file now on your desk top.
The main screen of the computer with the icons on it is called the "Desktop".
When you save a document, on the left of the "Save As" box it will say "Favourite Links". One of these is "Desktop". Click "Desktop" and then "Save". The document is now on the desktop.
