CCleaner, made by Piriform, cleans a computer’s registry setting and provides a software uninstallation service. It is well respected among these types of utility programs for its reliability and ease of use and our CCleaner review is positive.

CCleaner’s main function is to remove invalid references from a PC system’s registry. Unlike other similar registry cleaners, it is less likely to corrupt your system when cleaning your registry or deleting files and applications.

It also provides functions to fully uninstall software you may have installed on your computer but no longer use. It can also be used to clear unnecessary browsing data history and remove logs of your internet activity when accessing a public device.

CCleaner is currently available for computers running Windows 10, 8.1, 8, and 7 and runs on both 32-bit and 64-bit versions of these operating systems. It is also available on Macintosh computers running macOS 10.8 and higher and Android devices that are running version 5.0 or higher.
