CCleaner Professional – Key (1 Year / 1 PC)

CCleaner Professional is the best-known maintenance utility for Windows. Its principle is simple: go through the computer, spot everything cluttering it — temporary files, browser caches, installation logs, orphaned registry keys — and remove it in a single operation, entirely safely. The Professional edition adds automatic background cleaning and real-time monitoring of clutter. The licence covers 1 PC for 1 year. An important point: CCleaner is an optimisation tool, not an antivirus; it neither detects nor removes malware.

Main features

• System cleaning — temporary folders, recycle bin, thumbnails, error reports and uninstallation leftovers.
• Browser cleaning — cache, cookies and history for Edge, Chrome, Firefox and Opera, with the option to exclude trusted sites.
• Registry — detection and correction of invalid entries, with a backup offered before each pass.
• Faster startup — disabling of programs, services and scheduled tasks launched automatically.
• Smart cleaning — the Professional edition acts as soon as a threshold of junk files is crossed, without any action on your part.

Compatibility

Windows 11, 10, 8.1 and 7 in 32 and 64 bit. An internet connection is required to activate the licence and receive software updates.

Activation

Your activation key is sent by email within 24 hours at most after payment is confirmed. Open CCleaner, the “Options” menu then “About”, click “Upgrade to Pro” and enter the username and key provided. The licence is valid for 12 months.
