Using this simple keystroke, you can take a screenshot without any additional software. It’s free and built into Microsoft Windows!
Two methods exist for placing a copy of the current screen into the clipboard:
The Print Scrn key takes a screenshot and places it into the clipboard.
Pressing the combination of ALT + Print Scrn places the current active window into the clipboard.
Once your screenshot is in the clipboard it can be pasted and manipulated in any software graphics package. For example, you can paste this screenshot image into Paint for saving or editing.
Please note:
On many laptops, the Print Scrn key is actually Fn+Insert.
