To take full-size screenshots in Windows 10, press Win + Print Screen. You will see that the screen goes darker for a second. The screenshot is then saved in the Screenshots folder, inside the Pictures folder within Windows. If you press the Print Screen button without pressing the Win key, the screenshot is saved onto the Windows clipboard for you to paste into another app, or use later.
To take a custom-sized screenshot, Windows 10 has a built-in app called Snip & Sketch. Press Win + Shift + S to open Snip & Sketch. The screen will turn darker and the following interface appears at the top of the screen.
When the first box is highlighted (the color blue), you can drag your mouse over an area of the screen and take a rectangular-type screenshot. The second option allows you to take a curved or round-type screenshot. The middle option allows you to take a screenshot of the current window you have open. The fourth option allows you to take a screenshot of the whole screen. The last option allows you to close the app, or you can press Esc.
Once you take a screenshot, Snip & Sketch shows you at the bottom-right of your screen that it has been saved to the clipboard.
If you then click on that image, it will open up the screenshot in the Snip & Sketch app.
From here you can crop the image, pick a pen type and color, and draw on your screenshot.
You can also adjust the viewing size of the image, by clicking on the magnifying glass.
The options on the top-left allow you to take a new snip now, or automatically after 3 or 10 seconds. You can open a previous file, and cycle forward or back through any adjustments you have made.
Finally, you can save or print your work, and get access to other options, by clicking on the menu icon at the top-right.
