Acrobat Reader, a program from Adobe Systems, Inc., allows you to read and print documents in the Portable Document Format (PDF). While the program does not incorporate a feature that allows you to take screenshots of PDF files, it is possible to use Windows' "Print Screen" feature to do so. This feature allows you to save a portion of a PDF file to, for example, send it by email to a contact. You can take a screenshot of a PDF file in just a few steps.
Launch Acrobat Reader by clicking on the application's shortcut in the "All Programs" folder of your Windows "Start" Menu.
Click on the "File" menu at the top left of your screen. Select "Open" and locate the PDF file you wish to open. Click on the "Open" button to load it into Acrobat Reader.
Click on the "Window" menu at the top of your screen, and then select "Full Screen Mode."
Press the "Print Screen" or "PrtScrn" key on your keyboard.
Press the "ESC" key on your keyboard to escape full screen mode.
Open your Windows "Start" Menu. Type "Paint" in the search box. Press "Enter" to launch Paint, a free graphics-editing program.
Press the "Ctrl" and "V" keys simultaneously to load the screenshot into Paint. You can now save your file or edit it using Paint's editing tools.
