What is CCleaner?
CCleaner (formerly CrapCleaner) from Piriform Software Ltd is an all-in-one utility app designed to optimize the performance of your PC. It achieves this primarily by removing temporary “junk” files that can build up on your hard drive through regular computer use—often reaching several gigabytes—and by reducing the number of apps and services that automatically start running when you start up your PC or certain applications. This frees up space on your hard drive and allows programs to run with less strain on your computer’s RAM and other resources. CCleaner is available both as freeware and in a Pro version that includes some extra convenience features.
