Hereof, is CCleaner professional worth the money?
Overall, I think CCleaner Professional is a great PC cleaning tool, and worth the money. Even the free version is better than other cleanup tools like Avast Cleanup. However, like most PC cleaners, it won't actually speed up your computer. The only software that gave me noticeable results was Iolo System Mechanic.
Subsequently, question is, is CCleaner professional free? Professional Trial
Use CCleaner Professional for 14 days, for free. Once your trial is over you'll automatically drop down to CCleaner Free, so it won't cost you a thing.
Also question is, is CCleaner professional a one time purchase?
The price is shown as a one-time payment, with no time limit, and no mention of any extra fees. Clicking on the "Download" button for the Pro version takes you to the basket page, where the customer enters their order details and payment details, and again there is no mention of any time limit or extra fees.
What is the difference between CCleaner free and professional?
The differences between free and pro versions are mainly in scheduling, monitoring, and the cleaning of multiple user accounts. If you have the free version installed then go to 'Options' and look at the tabs for "Settings", "Scheduling", "Monitoring", and "Users".
