Addend to Nicole's note: If you use Alt-PrtScn you copy only the "active window." If you use PrtScn alone, you get everything on the screen.

If you use the "Alt" key with the Print Screen key, you'll get only the Explorer stuff - if that's what you have up.

I usually just paste (Ctl-V) screen shots directly into Word, since it's easier to "translate" things to text and make notes there.

When you paste a screen shot, of course it's a graphic. A little playing around with the graphics toolbar (in Word) will let you resize, relocate, flow text around the pic, crop, and such to make something that's more usable (sometimes) than the first paste image. For simple image editing, the graphics toolbar in Word is about as good as what you get in the simple picture programs like Paint.
