lo0ol...If you look carefully on your keyboard, you'll find a button saying: "PrtSc
Sys Req"
Just hit it. Go to paint. Ctrl + V. Save as. I think you can handle it from here.

I paste it on Word or Powerpoint so I can edit easyer, like crop it - I prefer croping it on Power point I find it easy, just Ctrl - V like on paint.
Paint is good for editing (eg, Blanking and drawing lol)
