  • Press Windows key + Shift + S to open the snipping overlay.
  • Select the type of snip: rectangular, freeform, window, or full screen.
  • The screenshot is copied to clipboard and opens in Snipping Tool where you can edit, save, or share it

• Using Print Screen key:
  • Press PrtSc (Print Screen) to capture the entire screen to clipboard.
  • Press Windows key + PrtSc to capture the entire screen and automatically save the screenshot in the Pictures > Screenshots folder.
  • Press Alt + PrtSc to capture the active window to clipboard

• Using Snipping Tool app directly:
  • Open Start, type "Snipping Tool," and select it.
  • Click New and choose the snip shape to capture

On Mac

Screenshots on Mac are saved to the desktop by default, and you can edit them by clicking the thumbnail that appears briefly after capture

. These are the most common and built-in ways to take screenshots on computers without needing extra software.
