Screenshots are used for a variety of reasons. They can be used as proof of something specific that has happened on your screen or to save an image of important information. The screenshot is an excellent resource for customer service and help desk representatives. If you receive an error while running an application, you can take a screen shot of it and send it to the help desk so they know exactly what has happened.
If you are using a desktop with a separate keyboard, press the "prnt scrn" key. This will store an image of the screen on the Windows pasteboard. You can then paste the image into an image editing program.
If you are using a laptop, the keyboard often combines keys, and when pressed in conjunction with a function key, performs a specific task. To take a screen shot on a laptop, press "Fn-Prnt Scrn." The screen shot can then be pasted into an image file through image editing software.
Most versions of Windows Vista and all versions of Windows 7 come with a Snipping Tool. To use this, click "Start" | "All Programs" | "Accessories" | "Snipping Tool." Drag your cursor over the area you want to capture. Choose a location for where you want the image to be saved and click "Save."
