Microsoft includes a flexible screenshot utility with Windows 10, called Snipping Tool. You can make use of Snipping Tool to get a screenshot and save as an image file.

1. To open Snipping Tool, type Snipping Tool in the search box on the taskbar, and then select Snipping Tool from the list of results.
2. In the “Mode” drop down, choose the kind of screenshot shape you want – you can select anything from rectangular  to full screen to a free-form shape.
3. Click New, and your screen will freeze. You can then use the mouse to create the screenshot. The screenshot will then appear in the Snipping Tool window.
4. If you want to include something like a tooltip, which only appears after a mouse movement, you can specify how long to wait before taking the screenshot using the Delay menu.
5. If you want to, once you’ve taken your screenshot, you can use the drawing tools to annotate the screenshot.
6. When you’re done, click “File” and then click “Save As” to save the completed screenshot to your computer.
7. You can also click the copy button in the Snipping Tool window – it looks like two pages laid over one another – to copy the image to your clipboard.
