CCleaner Professional 2025 – Key (1 Year / 1 PC)

CCleaner Professional 2025 is the current version of the maintenance utility for Windows. Its mission has stayed the same for years: free up disk space, wipe traces of use and lighten the system startup. The 2025 edition refines the automatic operation, improves support for recent browsers and presents a more readable dashboard of the machine's condition. The licence covers 1 PC for 1 year. A reminder: CCleaner cleans and optimises, but does not detect viruses — an antivirus is still needed separately.

Main features

• Full cleaning — temporary system and application files, caches, logs, thumbnails, installation leftovers.
• Browsers — Edge, Chrome, Firefox and Opera: history, cookies and cache, with a whitelist of sites to preserve.
• Automatic cleaning — the Professional module works in the background according to your rules, including when browsers are closed.
• Startup optimisation — disabling of programs, services and scheduled tasks that delay sign-in.
• Performance monitoring — putting to sleep the demanding applications that run needlessly in the background.
• Software updates — installation of recent versions of applications detected as outdated.

Compatibility

Windows 11 and Windows 10 in 64 bit, with maintained support for Windows 8.1. An internet connection is needed for activation and updates.

Activation

Your activation key is sent by email within 24 hours at most after payment is confirmed. Install CCleaner, go to “Options” then “About”, choose “Upgrade to Pro” and paste the key with the username indicated. The 12-month period then begins.
