How to take a snapshot of the contents on your screen?

All of us have noticed the button called ‘Print Screen’ (Prnt Scrn) at the top of the keyboard on the right side.  It will be usually located at the top row.

It is used to make screenshots of your desktop screen.  Whenever you want to capture your desktop as an image, just hit the ‘Prnt Scrn’ button once, and it will take an exact snapshot of your monitor screen.  Now, the screenshot is in the clipboard. How to save it?

Now if you want to save it, just  open the paint application. Paste the image which is there in the clipboard by pressing  “Ctrl+v”. The image is visible on the Paint window. Now if you want, you can edit it as you wish and save it.

Suppose you want to take a snapshot of one window on the screen but not the entire screen. How do we take it then? Let’s see. Make the window of which you want to take a snapshot, the active window. Just click on its title bar to make it active. Now, while holding down the Alt key, press the ‘Prnt Scrn’ button. You got a screenshot of your favourite window. Follow the procedure mentioned above to save it.

Hope this helps!
