Looking to do a screenshot? Not sure what to install? Open source software has you covered. Greenshot, supports multiple file formats and can screenshot full-screen, window, and region (section that you mark off) all at a touch of a mouse-click. Written in C# and licensed under GPL, you really can’t get any better than this. At the current posting, it’s so beta, that there isn’t an installer yet. But hey, what do you expect from beta software?
