CCleaner Reviews FAQs

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.

"Optimize and clean our equipment easily, quickly, and for free"
5/5
What do you like best about CCleaner?

The most relevant and important aspect of this tool called Ccleaner is that it allows us to perform a detailed analysis of our computer and system in order to detect and eliminate temporary files that enter our system without us noticing and that could affect the functioning of our equipment. It also has a control panel that allows us to see which programs we have installed and how frequently we use each program. Through this function, we can remove and add programs more quickly and easily. Ccleaner is undoubtedly an essential program because with its help we avoid damage to our computer and ensure it functions correctly and efficiently. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

This is an excellent program and I don't see any negative points about it. It is functional and helps keep our devices free of unwanted files, resulting in optimal and fast performance. Review collected by and hosted on G2.com.

"A great and effective tool to optimize my computer"
4.5/5
What do you like best about CCleaner?

What I like most about Ccleaner is that it is a very easy-to-use program, as just by opening the interface you can access the tools that Ccleaner provides you as a user. One of the tools I use most frequently is the one for cleaning the cache and temporary files that are stored on my computer and only take up space that I could use for more important things. Another important tool that this program has is the ability to see which programs I have that can be updated, thus providing me with a better experience by keeping me updated all the time. I can also remove programs that I no longer need in order to free up space on my hard drive.

Ccleaner automatically performs an analysis where it shows you how much space can be freed up with just one cleaning. In the Ccleaner options, we can change the language so that we can make even better use of the program. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

What I don't like about Ccleaner is that many of the best tools are reserved only for premium users. However, in the free version, there are many that can be utilized. Another thing I don't like is that whenever you perform an analysis, it asks you to close the browsers, and that's something I don't like because I'm usually doing something important on the computer. However, I can remove the browser I'm using from the list so that it doesn't affect its functioning while I'm using it. Review collected by and hosted on G2.com.

"Solution for the removal of SPAM files on our computers. Free"
4.5/5
What do you like best about CCleaner?

Ccleaner has allowed us to optimize our equipment at the company level and at the personal level, so we can protect them from temporary files, obsolete files that generate slowness in our tools that we use for our management at an operational and administrative level, making the best solution is that our LDA team generates updates in off-hours thus allowing proper operation; additional allows to validate the downloads made that are executed by the local user, generating a greater control of the management developed by our collaborators. This has allowed our computer equipment to be optimized for the most part, generating a more effective internal customer experience so that our end customers have the necessary satisfactions. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

The main limitation that Ccleaner had was its compatibility for different browsers (Chrome, Mozilla, Opera and Crytotap), this also generates some crashes of the same tool at the time that it is providing its scanner service generating a well-known error such as C00000021A What we could identify is that this happens when an update to the Ccleane is performed. however, IT Support has given us the most support to solve this, with support within its response SLAs.

"Ccleaner as a best solution to clean your PC"
4.5/5
What do you like best about CCleaner?

I really like that this program is easy to use. Once I download it, install it and start cleaning my computer. The first thing it does is delete the history and cookies, which take up unwanted space on my computer. Then I can clean the logs and this makes my computer go faster. This type of service is worth a lot. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

Many times this program asks for updates very often. I always agree to update, but I realize that the changes they make after each update are not very important, which makes me think why so many updates are needed. I think the company should consider giving this a change, for the better Review collected by and hosted on G2.com.

"A system cleaner that cannot be recommended anymore"
3/5
What do you like best about CCleaner?

CCleaner can bring about actual improvements with system performance and storage space on old PCs. It has a rich feature set that can remove unnecessary files taking up space on a PC. The UI is also intuitive. The free version also has most of the features unlocked. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

CCleaner bundles other software during installation, and it's not very easy to opt out of. The recent data breach and malware attacks only compound problems of the software. This means that people need to think twice before installing CCleaner. Review collected by and hosted on G2.com.
