What is CCleaner?
CCleaner Pro Piriform is a Windows cleaning and optimization program developed by Gen Digital. First launched in 2004, it has become one of the most popular Windows maintenance programs in the world. The Pro version enhances the capabilities of the free version with core features such as automatic background cleaning, scheduling cleaning, and comprehensive software and driver updates, eliminating the need for users to manually maintain their system every day.
CCleaner's strength lies in the comprehensiveness of what it can clean, from Windows junk files and hundreds of browser and program browsing history to duplicate disk files, unused Registry entries, and junk files from cloud storage services like Google Drive, OneDrive, and Dropbox. Everything is done through a user-friendly, one-click interface, but advanced users can also customize it extensively.
CCleaner Pro supports all Windows versions from 7 to 11, both 32-bit and 64-bit, including ARM64 architecture for newer devices. It also has versions for macOS, Android, and iOS.
