You may have realized by now that most freeware software come with third party bundles, which you may install by accident and mess up for instance your browser settings. Unchecky is a smart software that helps you uncheck such third party applications, toolbars or any unwanted attributes during the installation of a program. It expands all hidden components during an installation and unchecks them all. Also, when installing unknown software it warns you promptly and asks for further authorization. It does not have a conventonal interface and runs in the background, thus not bothering or loading your system at all.
