Join nowA 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.
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.
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.
To ensure optimal performance, your system should meet the following minimum specifications. Please note that these are general guidelines, and we always recommend verifying against the latest vendor documentation on the official CCleaner website.
Getting started with your CCleaner Professional licence is a straightforward process designed for immediate use. As soon as your payment is securely processed, you will receive a confirmation email and your Lizensa customer account will be updated with your licence details. This delivery typically occurs within seconds.
An active internet connection is required for the activation step. If you encounter any issues, Lizensa's multilingual technical support team is on hand to assist you free of charge. The licence allows for reinstallation on the same device, for example, after a hard drive replacement or operating system reset, using your CCleaner account credentials.
Choosing where to buy your software is as important as choosing the software itself. At Lizensa, we've built our entire service around trust, speed, and genuine EU compliance. When you purchase your CCleaner Professional 12 months licence from us, you're not just buying a key; you're securing a guaranteed authentic product sourced directly from authorised European distribution channels. This means no grey-market risks, no unexpectedly blocked keys, and full compliance with European Union consumer law.
The experience is built for immediate gratification and long-term peace of mind. Our automated delivery system sends your licence key to your inbox in under sixty seconds on average, so you can solve your PC performance issues right now.

For B2B customers with a valid EU VAT ID, the reverse charge mechanism is applied automatically at checkout.
Your transaction security is paramount. Our Stripe-secured checkout supports a wide range of European payment methods, including SEPA bank transfer, iDEAL, BLIK, Google Pay, and all major credit and debit cards, all processed with bank-grade encryption.
