There is a new way you can take screenshots in Windows 10 without additional third party tools! With the latest Creators Update, Microsoft added a new system-wide shortcut to allow you to select a specific area of the screen and copy it to your clipboard.
Press Windows + Shift + S in build 15063 (Windows 10 Creators Update) or later will trigger the gray out overlay that you can use your mouse to click and select a specific area. Once you have selected the area it will be get copied to your clipboard, you can paste the image into any editor or input that accepts an image from the clipboard, or you can open paint and save the screenshot from your clipboard.
Back in Windows 7, Microsoft introduced the Snipping Tool which does more or less the same. The slight difference between the Snippping Tool from Windows 7 and this new native method to capture a selective region on the screen is the missing system-wide keyboard shortcut. If you still prefers the Snipping Tool and would like to add a system-wide keyboard shortcut we got a tutorial for you here to follow.
If you are a Mac user, this is VERY much like Shift + Command + 4 on Mac the only difference is you don’t get an image saved at a default(desktop) location. So keep in mind with the new shortcut, you might find it useful and handy when you need to take a screenshot spontaneously.
