1. To take a screenshot of the entire screen, press the "Print Screen" (it could be labeled "PrtScn" or "PrtScrn") button on your keyboard. It can be found near the top, to the right of all the "F" keys (F1, F2, etc) and often in line with the arrow keys.
2. To take a screenshot of just the program that is active, press and hold the "Alt" button (found on either side of the space bar), then press the "Print Screen" button.
3. To view this screen-shot for further use, use Paint or some other graphics program. Do not use Microsoft Photo Editor; this program will only record part of your screenshot. When you are in Paint at a blank page click on "Edit" and then click on "Paste" and your screen shot will appear on the blank page.
4. To save, just go through the usual steps for saving a picture or graphics item (for example, click File, then Save As or Save.)
5. If you want to capture a window or dialque box click on the top bar of the window or dialoque box then holding down the alt button press on the print screen button. You then can press control v to add the window to a word processing program or presentaion program.
