CCleaner Professional is the premium, single-device version of Piriform's well-known Windows cleaner and optimiser, designed to remove junk files, fix registry errors, and improve overall system responsiveness. Compared with the free edition, the Professional licence unlocks scheduled and automatic cleaning, real-time system monitoring that can trigger cleans when certain conditions are met, and the ability to clean multiple user profiles on the same machine. It also includes a built-in Driver Updater to refresh graphics, sound, network, and other drivers, plus a Health Check tool that analyses the system and applies recommended fixes to speed up boot times and stability. Privacy-focused features clear browser history, cookies, and trackers from major browsers, while startup management lets users disable unnecessary programs to reduce boot time.
