CCleaner Professional 2023 is a maintenance utility for Windows PCs. It clears out what builds up unnoticed over time: temporary files, browser caches, leftover logs and registry entries that no longer point to anything. It also lets you control which programs start with Windows. The effect is most noticeable on older machines, which regain disk space and a more responsive system. This licence covers one PC for one year.
What the software does
- Disk cleaning: removes temporary files from Windows and applications, caches, thumbnails and the recycle bin contents.
- Browser cleaning: clears history, cookies and cached files in Edge, Chrome, Firefox and Opera.
- Registry cleaning: finds orphaned entries left behind by uninstalled programs, with a backup offered beforehand.
- Startup management: switch off programs and scheduled tasks that slow down sign-in.
- Automatic background cleaning: a feature of the Professional edition that runs once a threshold of junk files is reached.
