Original License Guaranteed by Licensel.com

CCleaner Professional is the world's most widely used cleaning and optimisation program for Windows: it removes junk files, cleans the system registry, manages startup programs and erases browsing traces. The Professional version adds real-time automatic cleaning and updates for installed programs. The license is annual and is delivered by email with the activation code.

Why choose CCleaner Professional

A Windows computer gradually accumulates temporary files never deleted, registry entries left after uninstalls and programs that start at power-on without being needed. Each weighs little, but together they lengthen boot times and reduce free space. CCleaner tackles all these fronts in a single operation.

The difference from the free version lies in automation: Professional works in the background and cleans when needed, instead of requiring the user to remember to run a scan now and then. It also adds automatic updating of installed programs, a useful function because outdated software is one of the most exploited entry points.

What CCleaner Professional is and what it is for

CCleaner Professional scans the system and identifies what can be safely removed: temporary files, browser caches, logs, thumbnails and registry entries that are no longer valid. Before acting it shows the list of what will be deleted and creates a restore point for the registry.

Alongside cleaning are the control tools: startup program management, uninstallation that also removes leftovers, disk space usage analysis and automatic updating of installed applications. All operations can be scheduled to run periodically, with no manual intervention.

Key features

• Real-time cleaning
  Unlike the free version, Professional acts automatically as junk files accumulate, without waiting for a manual scan.
• System registry cleaning
  Removes entries left after uninstalling programs, first creating a restore point so you can go back.
• Startup program management
  Shows which applications start with Windows and how much they affect boot times, and disables them without uninstalling.
• Complete uninstallation
  Removes the program together with folders, configuration files and registry keys that ordinary uninstalls leave behind.
• Browsing trace cleanup
  History, cookies and caches of installed browsers are cleaned in a single operation, with the option to exclude sites you want to keep.
• Automatic program updates
  Identifies installed applications running outdated versions and updates them, reducing vulnerabilities tied to unpatched software.
• Scheduled cleaning
  Set the frequency once and the program works in the background, keeping the system tidy with nothing to remember.
• Disk space analysis
  Shows which folders and file types take up the most space, useful when the disk fills up for no obvious reason.
