What This Tool Does for You

At its core, CCleaner Professional is a system surgeon. It performs three critical functions that directly improve your daily computing experience. First, it cleans, removing the gigabytes of temporary, junk, and log files that Windows and your applications accumulate. This isn't just about freeing up space; it's about removing the data that slows down file indexing and application loading. Second, it optimises. By cleaning the registry and giving you control over startup programmes, it tackles the root causes of system instability and slow boot times. A well-maintained registry means fewer crashes and cryptic error messages. Third, it protects. In an age of digital surveillance, CCleaner Professional acts as your privacy shield, thoroughly erasing your online and offline activity tracks. The built-in file shredder adds a layer of military-grade security for sensitive documents.

This is a permanent license for the current version. You can use it for as long as you like without any further payment. It is the ideal tool for a one-time system overhaul, a scheduled maintenance routine, or preparing a PC for a new user. It simplifies what would otherwise be a complex, manual, and technical process into a few safe, automated clicks.

Frequently Asked Questions

Is CCleaner Professional a subscription or a one-time purchase?

This is a permanent, one-time purchase license. You pay once and can use the software for the lifetime of that version without any recurring fees. This is a key advantage over subscription-based alternatives.

What is a Retail license and how is it different from an OEM key?

A Retail license is the standard consumer license designed for an end-user. It is transferable to a new PC if the old one is decommissioned (subject to the vendor's terms). An OEM (Original Equipment Manufacturer) license is typically pre-installed on a new PC and is non-transferable, tied permanently to the first machine it's activated on. This product is a Retail license, offering you greater flexibility.

How fast will I receive my license key after payment?

Our delivery is instant and automated. You will typically receive the email containing your license key and download link within 60 seconds of a successful payment confirmation.

How can I be sure this is a genuine, legal license?

Lizensa sources all software licenses exclusively through authorised European distribution channels. We provide a full VAT invoice with every purchase, which is your proof of a legally acquired license. We never sell grey-market or volume-license-split keys.

What should I do if I have trouble activating the software?

First, ensure you are entering the key exactly as provided and that your PC has an active internet connection. If the problem persists, our multilingual technical support team is available for free to help you troubleshoot and resolve the issue.

Can I reinstall CCleaner Professional or transfer the license to a new computer?

You can reinstall the software on the same PC as many times as you need, for example, after a Windows reset. As a Retail license, you may also be able to transfer it to a new PC, provided you completely remove it from the old one. For specific transfer limits, please refer to the vendor's end-user license agreement.

Will this license work in my country within the EU?

Yes. Our licenses are valid for activation and use in all 27 member states of the European Union. The software itself also supports multiple languages, including English, German, French, Dutch, and Polish.

What payment methods does Lizensa accept?

We offer a secure checkout powered by Stripe, accepting all major credit and debit cards, SEPA bank transfers, iDEAL, BLIK, and Google Pay.

Do you provide a proper VAT invoice for my business?

Absolutely. A compliant VAT invoice is generated and delivered with your license key immediately after purchase. For B2B customers with a valid EU VAT ID, a reverse-charge mechanism is available.

What is your refund policy?

In accordance with EU consumer protection law, you have a 14-day right of withdrawal on your purchase. However, as this is a digital product, the refund right may be voided once the license key has been delivered and activated. Please review our full terms and conditions for details.

Does CCleaner Professional include antivirus protection?

No, CCleaner Professional is a dedicated PC optimisation and cleaning tool, not an antivirus. It focuses on removing junk files, cleaning the registry, and protecting your privacy. It works perfectly alongside your existing antivirus software to keep your system fast and secure.

Is this version compatible with Windows Server?

CCleaner Professional is designed and licensed for standard Windows desktop operating systems (like Windows 10 and Windows 11). It is not intended for use on Windows Server editions. For server maintenance, you would need a specialised server tool.
