Many people don't know how easy it is to create a screen-shot in Windows.
Look for the PrtScn key located on the upper right side of your keyboard (you should see it after the F12 key). Now click the PrtScn key once. That's it, you've just taken a screen-shot of your desktop (no kidding). You're probably thinking, “Okay, great, now how do I make the screen-shot appear?”
