CCleaner is a free Registry and junk-clearing utility for keeping your system clean and optimized.
Pros
Basic UI: CCleaner's four main features -- Cleaner, Registry, Tools, and Options -- are clearly marked on a vertical tab menu. Initiating a scan and clean is straightforward.
Powerful: CCleaner includes most of the essentials for PC maintenance. It provides tools for clearing your temporary files, cleaning the Registry, and removing unused cookies from your browser. CCleaner also supports 64-bit systems, as well as updated support for popular applications.
Freeware: Upselling and bundling are minimal; CCleaner only offers the option to install Google Chrome, which users can easily opt out of. Compared to many other free programs, CCleaner is the least ad-heavy.
