Some reasons to take a screen shot capture while working are to inform tech support about an information technology bug issue, do collaborative design and create training documents. If the training documents includes a how-to guide, a screen shot capture will be beneficial.
A screen shot capture, which refers to a snapshot of a whole window display or part of it in JPG, can be performed using Windows utilities. For capturing an image on a Windows screen, the "Print Screen" button or "Print Screen" in combination with the "Alt" button can be used depending on the purpose for screen shot capture. There are also free software products such as Screenpresso 1.5.2 that can be downloaded for capturing a screen shot.
