CCleaner
A consumer maintenance utility that identifies selected temporary and application files for removal and offers additional system-management functions depending on the edition.
Overview
CCleaner presents categories of files and maintenance actions through a centralized interface. Its core cleaning workflow identifies selected temporary data, caches and other material that users may choose to remove. Additional tools have included startup management, application removal and other functions across different editions.
Cleaning categories have different consequences: a cache, saved session or browser record is not simply interchangeable spare data. The product's functions also change over time and by platform. A useful description therefore explains the operations rather than assuming that every suggested action improves performance or repairs a problem.

Historical significance
CCleaner became a prominent example of the consumer PC-maintenance market. It made otherwise dispersed cleanup controls easier to find, while also exposing the need to distinguish useful housekeeping from unsupported performance claims. Its commercial history shows how a focused utility can expand into a broader family of subscription and management services.
History and development
Piriform launched CCleaner in 2004. It grew alongside Windows systems accumulating browser data, temporary files and installed applications. The company later added related utilities such as Recuva and Defraggler.
Avast acquired Piriform in 2017, and CCleaner subsequently became part of the Gen group through later corporate changes. The product expanded into additional editions and services. Its history includes both widespread consumer adoption and scrutiny of the distribution, trust and practical value of maintenance software.
