Do you want to take a screenshot of a window on your computer? The Print Screen button lets you take a picture of whatever you are working on, and takes only seconds to use.
Press and hold the Function key (fn) and the Print Screen key (prt sc). The Print Screen key is on the top of the keypad between Pause and Delete, under Insert.
Click and drag to crop the area of the image, then let go of the mouse button to take the picture. A sound will play when the picture is taken.
Go to the Start menu, then Accessories, then Paint. Open your newly created image in the Paint program.
Make any edits to your image by going to the top of the toolbar and clicking on "Tools." Save your image.
Green Shot is an easy-to-use program that can do the same thing.
