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.

"fast and safe cleaning of temporary files"
5/5
What do you like best about CCleaner?

Its interface is very simple and does not require extensive configurations. It allows you to select which temporary files you want to delete or if you want to remove any unused system registry. It is compatible with the latest version of Windows, deletes files stored without any utility, and we can also get rid of the junk files that accumulate every time we surf the internet. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

I would not like to see more optimization tools. It is not possible to remove Windows packages that we do not use like other languages. Review collected by and hosted on G2.com.

"Optimize and Delete Temporary Files From Your Computer"
4.5/5
What do you like best about CCleaner?

I like this system because it allows me to delete and track documents and temporary files that are on your computer which we cannot see. I also like it because it contains a very functional tool that allows you to uninstall programs. Additionally, its interface is easy to handle and very easy to install. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

I dislike its price, I admit the software is of very good quality but the price is extremely high for regular people, also if you can't get the premium, the free version only lasts us one month, otherwise I have no more complaints about this software. Review collected by and hosted on G2.com.

"Free your Computer from Temporary Files"
4.5/5
What do you like best about CCleaner?

I like Ccleaner because it is a Complete and Robust program, it helps to optimize our computer and to delete all those stored files that we cannot see as a user. Ccleaner deletes what is called cookies, temporary files, and junk files that your computer tends to pick up while you browse the internet. Additionally, it has a tool that allows you to uninstall programs without needing to enter the control panel. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

I don't have much to complain about this wonderful tool, only that it seems somewhat expensive for the average user. Review collected by and hosted on G2.com.

"Improve Performance And Optimize Your Computer"
5/5
What do you like best about CCleaner?

As a computer software analyst, I have liked this software because it is robust and very comprehensive. I have tried many cleaning software, but nothing has worked for me as well as Ccleaner currently does. It allows me to delete temporary files, cookies, and junk elements within my computer that are sometimes not visible to the user. Additionally, it is very easy to use and very economical for the average person. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

It is a software that has no drawbacks, as it is complete at least for me. I consider it the best internal computer maintenance and cleaning software I have tried. Review collected by and hosted on G2.com.

"Free your PC from Temporary Files."
5/5
What do you like best about CCleaner?

I like this tool because thanks to it I have been able to completely clean my computer of junk files as it has helped me clean temporary files that we cannot see as well as files stored in the recycle bin. The internet search engines have wonderful options like we can uninstall programs using Ccleaner, and it also optimizes your hard drive's memory. It is worth mentioning that it is very easy to use for users. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

What I don't like about Ccleaner is that it comes in English, or maybe because I didn't know how to download and purchase my license it appears in English, but other than that I have no negative opinion about this software. Review collected by and hosted on G2.com.

"Excellent tool for cleaning and optimizing my computers 100%"
5/5
What do you like best about CCleaner?

Excellent tool which provides us with a great service for the maintenance, cleaning, and optimization of our devices quickly and safely for greater performance and a better level of functioning. It has the capability to eliminate any type of files that have no function on our devices. It features an easy-to-use interface and its analysis services for the complete cleaning of our devices are very fast and effective. This great program also offers us the option to uninstall any type of programs 100%, with a thorough analysis of our registry which will remove any junk files that might remain unused on our devices. It also gives us the option to personally configure the programs we want to start automatically when we begin using our devices, allowing us to deactivate any program that might affect the quick startup of our devices. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

This is a very comprehensive tool that contains a large number of advanced functions which we must know how to use, as we can affect the original behavior of our devices if we use them without any prior knowledge, which can cause modifications in our registry or system, which will later present as a serious error for the optimal functioning of our devices.

"Really awesome cleaner for PC"
4.5/5
What do you like best about CCleaner?

The feature of cleaning up all the temporary files is very useful for all the end-users using the application as it allows to speed up the system and maintain it properly. It also has an in-built monitoring tool which warns when there are too many items in the bin. It also assists in software uninstall and removal of debris left thereafter. The auto-updates and registry removal are also very useful. Alongside, it also performs disk management processes such as defragmentation and optimization. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

Sometimes it deletes certain parts of the cache which are needed by the system to work smoothly, deleting them causes page faults and requires reloading the pages into the memory, thereby causing a slight delay in performance at certain points in time. Review collected by and hosted on G2.com.

"Clutter Free PC"
4.5/5
What do you like best about CCleaner?

It's awesome that you can set CCleaner to clean your browser's history, cache, and other browser clutters when you close it. CCleaner can also be set to clean up every application clutter and all your PC's clutter at a scheduled time. My computer has always been responsive since I installed CCleaner. It also notifies you when you already need to clean up your PC if clutter is way too much before the specific time of auto cleaning. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

Well, CCleaner definitely made my PC fast all the time and I do not have any regrets buying it. Review collected by and hosted on G2.com.

"My PC and Mobile Stable"
5/5
What do you like best about CCleaner?

The best thing about this platform is that it helps me keep my team stable, and it significantly improves performance by freeing up annoying files that slow down my devices and sometimes make them sluggish. It also helps me update obsolete software and protects my privacy. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

It is the best cleaning software and it has never given me problems; on the contrary, it gives me the best peace of mind when browsing on my PC, because it is always stable and fast. Review collected by and hosted on G2.com.

"Great For Removing Computer Clutter"
4.5/5
What do you like best about CCleaner?

Most tools I use always leave temporary files which eat up more SSD space and make those tools pretty damn slow when I use them again. Good thing CCleaner can clean up that waste and make my PC faster with just a single click. CCleaner also has features I rarely use, but are pretty important, like Registry Cleaner, software uninstaller, and other tools like duplicate finder and disk analyzer that can make your computer pretty damn fast as if it were brand new. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

More of a caution as I never read and thought that it could complicate things. If you do not know what each setting means, never use it. Just leave it as it is. I checked everything before and have deleted some necessary files I need. Review collected by and hosted on G2.com.
