Windows - How to take Screenshots
This document describes how to capture an image of the screen in Windows (all versions).
* Press the PrintScreen key on the keyboard to capture an image of the entire screen and store it in the Windows clipboard.
* Press Alt-PrintScreen to capture an image of only the active window and store it in the Windows clipboard.
When the desired image is stored in the windows clipboard (only one image can be stored at a time), it can be extracted by opening an image manipulation program (such as Microsoft Word, Adobe Photoshop or Microsoft Paint), and selecting Paste from the Edit menu.
