About this licence
CCleaner Professional 12 months – Streamlined PC maintenance for a full year
A sluggish computer isn't just an annoyance; it's a drain on productivity and a signal of underlying system clutter. CCleaner Professional is the globally recognised solution that tackles this head-on, automatically clearing the digital debris that accumulates through everyday use. This 12-month licence provides a complete, no-nonsense toolkit for Windows, designed to restore snappy performance, protect your privacy, and extend the useful life of your hardware. It moves beyond the basic free version by adding intelligent, real-time monitoring and scheduled cleaning, so your system stays optimised without constant manual intervention.
This annual subscription is purpose-built for a wide range of users. For home users and families, it's a simple way to keep multiple PCs healthy. Freelancers and remote workers will appreciate the reliable, hands-off maintenance that keeps their primary work tool running smoothly. IT administrators and small business owners can deploy it as a standardised, EU-compliant utility for maintaining a fleet of Windows workstations, with the 12-month term aligning perfectly with annual budget cycles and software audits. The core benefit is peace of mind: knowing your system is continuously cleaned, monitored, and optimised by a trusted, industry-standard tool, backed by a genuine licence and professional support.
Key features and benefits
Automated cleaning & intelligent scheduling: Set a cleaning routine—daily, weekly, or monthly—and let CCleaner Professional work in the background. It safely removes temporary files, browser caches, and system logs, freeing up valuable disk space and preventing performance degradation without you needing to remember a thing.
Real-time system monitoring: Unlike the free version, Professional actively watches your system. It alerts you the moment junk files accumulate to a level that could impact performance, allowing for immediate, one-click cleaning before your PC slows down.
Privacy protection & browser cleaner: Erase your digital footprint across all major browsers, including Chrome, Firefox, Edge, and Opera. You can clear browsing history, cookies, and cached files, with granular control to keep saved passwords and form-fill data intact. This is essential for protecting sensitive client data or personal information.
Registry cleaner & system stability: Over time, the Windows Registry can become cluttered with invalid entries, broken shortcuts, and orphaned DLLs, leading to error messages and instability. CCleaner Professional scans for these issues and safely repairs them, helping to maintain a stable and responsive operating system.
Startup manager for faster boot times: Take control of programs that launch when your PC starts. The startup manager clearly shows the impact each application has on boot speed, allowing you to disable or delay resource-hungry apps and get to work faster.

Complete drive wiper: When you need to securely delete sensitive files, the standard delete function isn't enough. The Drive Wiper feature overwrites data multiple times, making it unrecoverable, which is crucial when repurposing or disposing of a hard drive.
Automatic software updates: CCleaner Professional keeps itself up to date automatically, ensuring you always have the latest cleaning algorithms, security patches, and feature improvements without manual downloads.
Priority customer support: Gain direct access to CCleaner's dedicated support team. Whether you have an installation query or a technical troubleshooting question, priority support ensures you receive faster, more in-depth assistance.
What's included with your purchase
When you purchase the CCleaner Professional 12 months licence from Lizensa, you are acquiring a genuine, digitally delivered software subscription for one Windows PC. Your order is processed immediately, and you will receive a clear, actionable email containing your unique licence key and a direct download link to the official CCleaner installation file. A detailed activation guide is included, walking you through the simple steps from installation to full activation.
This is a 12-month subscription licence, meaning the software is fully functional for one year from the date of activation. It is not a lifetime or permanent licence. The licence is for commercial or personal use on a single device. You will also receive a full, EU-compliant VAT invoice in your Lizensa customer account, which is essential for business accounting and tax purposes. The licence is tied to your CCleaner account (free to create), which manages your subscription and allows for easy reinstallation on the same device if needed.
What this tool does for you
At its core, CCleaner Professional is a comprehensive system health and privacy suite. It performs a deep clean of your PC, targeting four key areas that degrade performance over time: junk files, browser data, the Windows Registry, and startup programs. By automating these tasks, it transforms PC maintenance from a forgotten chore into a seamless background process.
For a non-technical user, this means a faster, more responsive computer without needing to understand what a temporary file or a registry key is. For a professional, it means a stable, reliable workstation that protects client confidentiality by securely erasing online tracks. The 12-month licence provides a full year of uninterrupted service, including all feature updates. At the end of the term, the licence can be renewed to continue receiving the Professional features, real-time monitoring, and priority support. Without renewal, the software will revert to the limited functionality of the free version.
