CCleaner (; originally meaning "Crap Cleaner"), developed by Piriform Software, is a utility used to clean potentially unwanted files and invalid Windows Registry entries from a computer. It is one of the longest-established system cleaners, first launched in 2004. It was originally developed for Microsoft Windows only, but in 2012, a macOS version was released. An Android version was released in 2014, and an iOS version was released nine years later.
