I see quite a few people in here taking mobile phone pictures of their screens when they need a screen shot.
There's a better solution for the need called "Print Screen"
There's usually a dedicated button on a full keyboard. Press this once when you need a sceen shot.
Now you go to "Start" / "Accessories" / "Paint" and press "Ctrl + V" - You now have the screen shot in an image editor
Now you click the button called "crop" and square out the part of the screen shot of interest and click "crop" again. Now only the selection is left.
Save that and you have a top notch screen shot
