Generated using AI

Last updated: Nov 01, 2026

What is CCleaner, and what problem is it built to solve?

CCleaner is a computer-cleanup utility used to remove temporary files and browser data that build up and take up disk space. Users also turn to it for routine maintenance when clutter is affecting how smoothly a computer runs.

What company sizes and industries is CCleaner the best fit for?

CCleaner is used across small businesses, mid-market organizations, and enterprises, with the clearest concentration among small businesses. Positive use is also visible across several technology-focused industries.

What customer support options does CCleaner provide, and how do users find the overall support experience?

Support has been described as professional and clear when resolving issues, but complaint handling has also been criticized as slow.

What features or capabilities could make CCleaner even more useful?

The most useful improvements would make the more advanced cleanup tasks safer and give users more control over what gets removed.

Is CCleaner considered safe and secure for handling data?

CCleaner is used for cleanup and clearing browser traces, but users do not treat it as a replacement for antivirus protection. Confidence is mixed: users value its privacy-cleanup functions, while others raise concerns about data handling and past security issues. Care is also warranted with registry and file-cleanup settings, since removing needed items can cause problems.

"I like that Cleaner is a program that inspires confidence"
4.5/5
What do you like best about CCleaner?

I like that Cleaner is a program that inspires confidence, in all the years I have been using this program, I have not had a single inconvenience. Every time I use it, the operation of my computer improves significantly, and the best of all is that Ccleaner is a customizable program. It is essential that any software at present be flexible and adapt to the needs of its different users, and Ccleaner does this perfectly. In fact, it has an option to customize the cleaning scheme of our computers, which we are going to use for each occasion. We choose which elements we want to eliminate and what we want to keep; we simply do not select them, and this configuration is saved for future occasions until we change it again according to our needs. I also like that the elements to be selected for our cleanings are presented in the form of a well-organized and categorized list. It is quite friendly and super easy to use.

What do you dislike about CCleaner?

It's great to be able to use a program like Ccleaner by customizing it and adapting it to our particular needs. Everyone has different things in mind and everyone gives a different use to their equipment, but it is a bit delicate and you need to be very careful when customizing our cleanings, because you can remove elements from the computer that are necessary for them to function properly, and this can damage our equipment or at least cause a bad time and a great scare. So it is good to know in advance what we are doing and be sure to take the time to customize and schedule our cleanings with Ccleaner. Review collected by and hosted on G2.com.

4.5/5
What do you like best about CCleaner?

Previously I have used competitive programs to clean my computers, without obtaining 100% satisfactory results and not all of these programs are reliable, many of them can cause damage to our computers. Thanks to Ccleaner I forget this problem, because it is a 100% reliable program that has shown me that it works very well, at the moment of having used it, just by cleaning more computers, using Ccleaner, my computers start working fast and properly, satisfying my work needs and without causing any headache, so use Ccleaner several times a day, every day, for my personal computer and for my computer at work and day after day I have only obtained good results. I clean history, cookies and other elements that are unnecessary but that occupy resources and spaces on my computers and everything is going very well, it is easy to use.

What do you dislike about CCleaner?

I do not find anything wrong with this program, it works very well and as expected, achieving the cleaning that my computers require quickly and reliably, every time I use it, the operation of my computers improves dramatically, so I have nothing bad to say in relation to Ccleaner, it is easy to install and very easy to use.

I like a lot of ccleaner and I think it is excellent since it really is a computer utility that fully fulfills the functions for which it was created, Ccleaner has a very intuitive system, effectively optimizes the PC, it is very easy to analyze and clean browser data, Temporary files and at the same time verify problems with the Windows services, and the records and now with a new plus such as the software updater makes the related daily tasks even easier and all in the most comfortable, fast and accurate way. It is noteworthy that I also use the application on my smartphone with Android 9.0 Pie operating system and it works just as excellent. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

What I dislike is that sometimes the cleaning operation takes much longer than expected, which generates a bit of discomfort and anxiety and as a suggestion I think we should use the application very carefully, since a bad use of it can to generate serious damages in the operating system of our PC, we must know it to make good use of it, otherwise I affirm to be completely satisfied throughout these years of use.

"Delete all junk files from your computer."
4/5
What do you like best about CCleaner?

With this program, you can instantly delete all the cache or junk files that are stored on your computer or mobile device, causing it to become somewhat slow. One of the advantages of this program is that it is completely free, very lightweight, and consumes very few resources from your device. This program is capable of deleting any file you want and uninstalling applications or games from your device. It is available for the most used platforms due to its excellent performance, as it is essential to have a cleaner as efficient as Ccleaner on your device. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

This program, being so good at deleting files, can also be somewhat dangerous at the same time, as you might delete an important operating system file, causing total chaos, so use this application responsibly and with utmost care. Review collected by and hosted on G2.com.

"Ccleaner cleaning of files trash par excellence."
4.5/5
What do you like best about CCleaner?

The constant use of internet is bringing with it the accumulation of many temporary files, invalids, added to the cache, search histories, cookies and many other types of junk files can occupy a lot of memory space on our hard drive, with Ccleaner I get rid of this problem because I can remove them whenever I want. It provides the option to analyze broken files and repair them, which can improve the performance of the computer. This application has very interesting features, one of them is that it shows me the characteristics of my processor and the size of my RAM, very useful data when installing certain applications so I can know if it will be compatible or not. Another is that it shows me a list of the programs I have installed in my computer and from there I can uninstall or repair them. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

Ccleaner has drawbacks when uninstalling certain programs, because clicking uninstall loads the uninstall process bar but in the end the program is still on my computer so it is quite annoying. Review collected by and hosted on G2.com.

"Best Windows Desktop - Laptop Cleaning Software"
5/5
What do you like best about CCleaner?

I have been using this software for more than 5 years. This utility tool really helps you to get rid of Windows desktop - laptop slowness problems. I use this software tool to clean (Temp files, Junk files, Disk Cleanup, uninstall software, Startup clean, etc.) and maintain office desktop PCs, etc. Piriform's CCleaner has Easy Clean features which will help you fix your computer in a single click. You can analyze your junk files and clear them with a single click. Also, it has a custom Clean option where you can include-exclude your choice for cleaning Windows and applications (temporary internet files, history, cookies, recent URLs, Windows temp files, recycle bin, memory dump, etc.). You can clean your registry in a single click. Basically, it will optimize and speed up your device in a few seconds. CCleaner can be used in small to large industries.

"An ideal software to keep your computers in good shape"
5/5
What do you like best about CCleaner?

CCleaner is an amazing tool because it allows me to clean my computers of all kinds of junk documents, it also helps me a lot to optimize the performance of my computers, all the tools of this software are very good and useful, the custom cleaning tool is great to debug specific documents and files on hard drives. The Registry tool is also ideal for finding and solving problems that cause conflict with the operating system. CCleaner has the ability to Repair and Uninstall programs that we do not use. In general it has a very simple interface to use and we can install it in different operating systems without major problem. Review collected by and hosted on G2.com.

I have used this software for many years and it does not have many problems, it has remained stable versions over the years. The only problem is that they have not added such radical changes to increase program performance. Review collected by and hosted on G2.com.

"Cleaning of the PC and increasing performance"
4.5/5
What do you like best about CCleaner?

Using a software as helpful as Ccleaner offers other advantages to my machine, because it helps me to constantly clean up search history, cookies and cache space, and creates greater fluidity while searching. Besides, the software has a very powerful system capable of deleting software that I no longer need, leaving space on the computer's hard drive, and if we get a Premium edition, it has a very popular tool that makes it easy to patch software that are out of compliance and thus reap all the benefits that the program can bring. The most important benefit is that it periodically displays a message that informs me when the room is filled and that we can eradicate it with a superficial analysis. With Ccleaner correctly, I will hold my machine streamlined, and that allows me a better experience because the screen doesn't freeze. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

Unlikely, I don't like about Ccleaner that there is actually no alert when the software is out of date, then one should search manually if there are any more modern variants of Ccleaner. Besides, the software concerns me a little that the trial model is very limited in comparison to the paid version. Review collected by and hosted on G2.com.

"It also has an option to clean your machine's records"
4.5/5
What do you like best about CCleaner?

CCleaner is a very simple program with which you can clean your computer. It has a free version and another paid. I really like both, but preferably the paid version. One of the things that this program offers you, is that you can make a rune for cleaning your personalized equipment, with which you delete the extra files and cookies. It also has an option to clean your machine's records. The good thing about this program is that your computer will thank you Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

This program is updated very often. I understand that this manages to correct errors of the current version, but it can still be somewhat annoying. There are very marked differences between the free version and the paid version. Obviously, the paid version offers better and more benefits. The free version is just a program that helps you clean your computer, deleting unnecessary files and getting more space on your hard drive Review collected by and hosted on G2.com.

I like its well distributed interface has excellent features to improve the performance of our team. It has a registry repair and real-time monitoring system.

What do you dislike about CCleaner?

It has no effective characteristics to improve the start of the window and the applications that are installed. Review collected by and hosted on G2.com.
