The Difference Between a CCleaner Professional key 2021 vs 2022

A CCleaner Professional key is an activation code that we provide customers when they purchase the software. Every person gets their own unique sequence and that way we know who is using the software and to send updates when we release them. These updates can be improvements to the performance of the software or even brand new features we add to the package.

Why do you still see CCleaner Professional key 2021 on some sites?

If you see a CCleaner Professional key 2021 being offered for free then this will be from a warez site or BitTorrent. Unless you are signing up for a package via our website or a trusted site you can assume that you’re downloading cracked (pirated) software. This has the potential to be very dangerous to your computer and personal data and could lead to:

  • malware or spyware on your computer
  • a ransomware attack
  • a virus
  • personal data or files stolen
  • stolen credit card or bank information
  • stolen website passwords or account details
  • other digital data stolen, like your web browsing history
  • a keylogger recording what you type so cybercriminals can blackmail you

If you download a cracked version this means you will get a fake activation key with it. While these keys themselves may not be infected with anything malicious, the software itself can be manipulated before it’s loaded onto a site. Another potential risk is the sites where these keys are found. They often redirect unsuspecting users to dangerous sites or have popups containing malicious content.

As we mentioned earlier, we regularly update our software to keep it running smoother, faster, and safer. Plus, we occasionally bolt on a new feature for no added cost if we think it will benefit our customers. If you download a version called “CCleaner Professional key 2021” from an untrusted site the software won’t include all the most recent safety updates and benefits.

How has CCleaner Professional changed?

Our developers made regular adjustments throughout 2021 to the software but the biggest development was the addition of the Driver Updater tool. It helps keep all of your drivers up to date which are critical for your sound, visuals, internet connection, and essential hardware to function. This will be missing in many of the fake keys distributed in 2021.

Driver Updater is particularly useful to any gamers out there or creatives who use big programs. If you want to try Driver Updater it’s part of our CCleaner Professional package and you can sample all of the tools it holds for free.

How can I claim my free CCleaner Professional trial?

All you need to do is click on “Free Trial” and your download will begin. There’s no need to enter any card details or even your name. It’s completely obligation-free so if you decide you don’t want to buy the software at the end of your 14-day trial, you’ll simply be moved onto the free CCleaner version.

Our CCleaner product is the number one PC-cleaning tool. Whether you just need the free version for a quick tidy-up or the full CCleaner Professional package, we think you’ll love what they can do for you. That’s why we have both options available here so you can easily decide which is right for you.
