How to Take Screenshot and Save as file
You can save as file whatever you are looking on the screen, all you have to do as described below:
Press the PrintScreen key on the keyboard. This copies a bitmap of the full screen into the Windows clipboard(Ram).
You need to open MsPaint and paste …Then you can save it as a .jpg or bmp etc
Alt + PrintScreen will capture only the active window.
This is good when you just need only active window.
