The easiest way would be to take a "picture" of the screen and save that in Word (or in Paint). I often do this to save on line forms.
Display the window you want to save and make sure it is the "active" window if you have more than one showing (select the border of the window to make it active and it becomes dark blue)
Hold down the Alt key then press Print Screen button.
This saves the active window and will copy a picture of the window to the clipboard.
Open Word and select Edit then Paste.
This should paste the screen shot into Word.
You could also Paste it into Microsoft Paint and save it as an image (bitmap, jpeg or GIF)
To save the whole screen rather than just the active window DONT hold down the Alt key but just press Print Screen.
