The screenshot above was taken using Screen Recorder Studio, a free program for Windows.
Not only it enables you to save any captured screenshots in 2 easy clicks, but also allows to record screen video and upload it to YouTube. What's more, the feed from your webcam can also be captured!
When recording video or saving a screenshot, you can easily select an area, draw arrows, lines, shapes, as well as enter some text.
In the paid Premium version, no ads are displayed, screenshots can be uploaded to your own server via FTP, and there are no time limits for video recording.
