CCleaner Professional Plus 2026 – Key (1 Year / 3 Devices)

CCleaner Professional Plus 2026 brings together the full set of maintenance utilities in the range within a single licence valid across 3 devices for 1 year. The cleaner frees up space and lightens the Windows startup, while the associated tools cover the recovery of deleted files, the defragmentation of mechanical drives and a full hardware inventory. It is the most suitable package when several computers need to be maintained with the same licence. CCleaner remains an optimisation tool and not an antivirus.

What Professional Plus 2026 includes

• Deep cleaning — temporary system and application files, browser caches, logs, thumbnails and uninstallation leftovers.
• Automatic cleaning — background monitoring that triggers the tidy-up according to your rules, in particular when browsers are closed.
• Startup optimisation — disabling of programs and scheduled tasks that lengthen sign-in.
• File recovery — restoration of documents, photos and videos deleted by mistake on a drive, SD card or USB stick.
• Defragmentation — reorganisation of data on mechanical hard drives to reduce access times.

Compatibility

Windows 11 and Windows 10 in 64 bit, with maintained support for earlier versions depending on the modules. 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. On each of the three machines, install CCleaner, open “Options” then “About” and “Upgrade to Pro” and enter the username and key provided.
