CCleaner

CCleaner is a system maintenance utility for Windows that scans for temporary files, browser cache, cookies, and other accumulated clutter, then deletes them to reclaim disk space. It also includes a registry cleaner, a startup program manager, and a tool for uninstalling installed software.

The free version covers these core cleaning and maintenance functions along with a basic system health check. The paid tiers (Pro, Pro Plus, and a bundled Premium package, all sold as one-time purchases) add automatic scheduled cleaning, driver updates, cloud storage cleanup for services like Google Drive and OneDrive, and bundled utilities for deleted-file recovery and system inspection.

CCleaner suits users who want a straightforward way to clear out temporary files and manage startup programs without digging through Windows settings manually. Users who only need occasional disk cleanup may find Windows' built-in Disk Cleanup or Storage Sense tools sufficient without installing third-party software.
