IObit Uninstaller deserved its place in my list for 3 reasons. First is amazing and super user-friendly interface. Second is browser add-on removal feature. And the third one – it is FREE. And of course, it is doing its main job greatly, searching for leftover files. Forced uninstall feature is also present. It also has useful feature for Windows 8 – ability to uninstall Windows 8 apps and clean their leftovers.
