How to capture a screen shot and save it as an image:
Why use freeware and risk spyware bundled with it. Or compy space. Just Alt+Print Screen, then open Paint.
Then Ctrl + V, click yes. Then, you can save your image as a JPEG. If you want only a part of it, crop it using the "Select" option, aka the dashed-square, one of the left buttons. Then copy, open a new paint pad, paste in the cropped portion of the image, Save As, and you're set!
