Greenshot
A great replacement for the print screen feature. Greenshot gives you a selection rectangle that allows you to select a certain area on your screen and do a range of things with it, including uploading your image to Imgur, saving it to your computer, opening it in an image editor and more.

You can download it here.

ShareX is, in my opinion, the best screenshot/basic recording utility available for windows.
