Evolving at the pace of the market, CCleaner has not stopped improving its functionality release after release for the last 10+ years. A reference among the myriad of system optimization tools right from the start, this free utility can keep your PC free from all types of junk and unnecessary files, maintain your Windows registry in top condition, find duplicates, and restore your system, with just a few clicks.

CCleaner still stands out from all the other free system maintenance programs available for various reasons. The first and most important reason is that it not only works and delivers as promised, but it is also a safe tool. All system optimization tools pose a risk, especially when used carelessly on such sensitive items as the Windows registry. Well, with CCleaner you will not have to worry about your system’s integrity, regardless of the task you ask the program to perform. Though I recommend you to take advantage of the registry backup that the program offers before making any changes – you never know what may cause your PC to turn off in the middle of the optimization task – I have never needed to make use of that backup file in the many years I’ve been using CCleaner.

Other good reasons to use CCleaner are the high speed of its various optimization tasks, the thoroughness of the subsequent reports, the extensive information about your drives and their contents, the possibility of checking each issue before fixing it, its browser custom cleaning tasks, its startup manager, and that inner calm that results from knowing that your PC is in the best of hands. more

Have full version, very good product! Could have more features for system optimisation though, like offering a driver update package (like it gives recuva e.g separately), though it is excellent for what it does.

Bjorn I, no way on using CCleaner to update drivers. I did that two years ago (in 2021) on a laptop with Windows 10 and one of the driver updates through the program caused BSOD. Being I was not doing driver updates individually myself, I never could figure out which driver update in particular caused it but it took me all weekend to even get to the point where I could even reinstall the OS because Windows 10 required administrator and WiFi access. But the WiFi was knocked out so I could not sign in and verify my credentials. It's a miracle the laptop did not need professional repair. I steer clear of ever even clicking driver update on newer versions of CCleaner. In fact, after what happened I prefer using older versions now before it was a feature. I would just like to see it removed entirely after this experience. Otherwise, CCleaner is an excellent program.
