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.

"The fastest way to clean your machine"
4.5/5
What do you like best about CCleaner?

Here are just a few software packages that offer a lot of confidence to Pine Tree State, like Ccleaner, with several positive aspects that help clean junk files and cache that always drag down our computer, often without us knowing. I particularly like Cleaner because at intervals the application has two tabs, which are programs and Windows, that allow Pine Tree State to uninstall exactly what I want from the system while not making me lose information like saved passwords. On the other hand, I like to uninstall and rename software that I have on my laptop from the list of devices. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

Mainly what I don't like is that often we want to make the machine like new and in the system cleaning tab you don't have the option to uninstall anything or you have to check all the boxes manually, and sometimes it's annoying to have so many classifications of junk information.

"CCleaner - Clean not only your C disk..."
4/5
What do you like best about CCleaner?

Internet use is persistent which ensures that many transient data, disables, search history, cookies, and several other garbage file types accumulate on our hard disk drive so I eliminate the issue with Ccleaner because I can delete them whenever I want. It offers the option of review and restoration of damaged files that can boost machine efficiency. One of them being that I am shown the features of my cpu and the capacity of my RAM, details rather helpful for running any programs so that I can see whether or not it is compliant. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

Cleaner provides disadvantages when it is uninstalled as uninstall clicks fill the uninstall tab, but at the end of the day, it is still on my machine so it is really anxious. Review collected by and hosted on G2.com.

"Great pc cleaner."
5/5
What do you like best about CCleaner?

Particularly, I like it because it is a reliable and safe software that works perfectly on any computer, whether high and low performance, allowing to completely eliminate all files that are useless, which are no longer used by the system and produces a low In performance, this is a very powerful software and one of the most used today. Its handling is very easy, it is used in a very simple way that anyone can get to use. It should be noted that it is a program that specializes in making a very specific and detailed analysis of our particular computer, both at the level of software and hadware eliminating cookies from browsers and other junk files resulting from uninstallations, the contents of the trash recycling, temporary files, among others. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

It is a program that must be used in a very careful way, because a mishandling can lead to the elimination of important files getting to have problems with the operating system and the only way to fix that problem is the reinstallation of the same. Review collected by and hosted on G2.com.

"Basic program with which to perform all computer cleaning tasks."
4.5/5
What do you like best about CCleaner?

Ccleaner is an essential tool for cleaning the PC that works properly even on the most modest computers and includes in a single program functions aimed at optimizing computer cleaning, improving PC startup, optimizing the registry, and features an application uninstallation assistant. The program is organized based on four basic aspects:

-The cleaner allows you to easily delete temporary files that slow down the computer, as well as cookies from websites we have visited. Its operation is very simple, we just need to check the boxes we want to be cleaned, and to delete them, it will only be necessary to click on Run the cleaner. The cleaner includes advanced cleaning options (for basic users, it is advisable to leave these options unchecked).

-On the other hand, the registry section allows us to correct any errors or corrupt entries that exist in our system's registry. It also detects obsolete shortcuts or those we haven't used in a considerable time. Its operation also stands out for its simplicity, by default all the boxes are already checked in the program, so it is only necessary to click on search programs; once the program has performed the relevant checks, we will be allowed to repair any problems. The program itself will ask us if we want to make a backup of the registry changes, once this backup is made (it is always advisable to use this option provided by Ccleaner in case any error arises) we will only have to repair the registry problems we wish. Finally, it is advisable to repeat the error search at least a second time, to ensure a correct solution to the problems.

-The tools section allows us to manage all the programs we have installed on our computer. In this sense, it allows us to uninstall any program safely, delete system restore points, and erase any startup process that may slow down our PC.

In conclusion, Ccleaner is an essential program on any computer, in a simple way thanks to its design it allows us to solve those performance and file deletion problems that many users suffer from. It is noteworthy that any user, including the most basic, can use the program and understand its functions instantly. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

One must exercise caution as improper use of this program can lead to modifications in the system registry that result in serious errors, the only solution for which may be a complete reinstallation of the operating system. However, this would undoubtedly be due to user misuse and not attributable to the program itself. Review collected by and hosted on G2.com.

"Great software"
5/5
What do you like best about CCleaner?

It's a small program that does a lot to keep your device running smoothly. It's like a window to the running OS. I can manage all my programs and even uninstall if required. I can run an analysis to check how much free space I can clear as well as fix reg errors that can create crashes or error messages. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

I have not come across any negative aspects yet. It offers several installation options and is value for money. I use the free version at my home and have found that it is can run on a very small capacity pc and still make a difference. Review collected by and hosted on G2.com.

"Ccleaner a new novel application"
4.5/5
What do you like best about CCleaner?

A tool that undoubtedly offers a wide range of options and does not take up space on the computer. It has good quality graphics and bright colors that appeal to users.

What do you dislike about CCleaner?

Despite being a simple cleaning tool, you need to know its mode of use, because we run the risk of losing the desired content, this being a common problem of many cleaning programs, I do not consider it a disadvantage, on the contrary, it is an incentive to learn more about this tool.

"CCleaner, cleaning of junk par excellence."
4.5/5
What do you like best about CCleaner?

I really like cleaning and I think it's excellent because it is truly a software tool that fulfills the functions for which it was designed. The Cleaner has a very intuitive interface, optimizes the PC effectively, and it is very easy to analyze and clean browser data, temporary files, while also checking for issues with Windows services and registries. Now with a new advantage like what it is. It's worth remembering that with the Android 9.0 Pie operating system, I still use the program on my smartphone and it works just as excellently. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

What I don't like is that sometimes the cleaning process takes much longer than expected, which causes a bit of discomfort and anxiety, and as a recommendation, I think we should use the program with great care, because misuse of it can cause serious damage to our PC's operating system, so we need to know it to make good use of it, otherwise I will say that I am completely satisfied.

Although it is a basic cleaning device, you need to know how to use it, since we run the risk of missing the desired content, which is a common issue with many cleaning systems, I do not find it to be a disadvantage; on the opposite, it is a reason to learn about this product.

"I like CCleaner, which is a lightweight program, which does not require much use of RAM"
4.5/5
What do you like best about CCleaner?

I like CCleaner, which is a lightweight program, which does not require much use of RAM, and allows you to have your computer clean and with an acceptable speed. The favorite function of CCleaner, is when the one where you can program the program so that every time you close the browser you are using, it activates and cleans the cookie computers. Of course, this only works in the paid version. Ccleaner is constantly updated and you will always have the latest version of the program available, which is positive because you need the version you use to be the most advanced. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

There are many differences between the paid version and the free version. For example, the paid version allows cleaning programs and the free version does not. Although updates are necessary, many times I feel that this program presents updates very often and to be updating the program, at all times, it is annoying Review collected by and hosted on G2.com.

"I think this is the program that I have used the most and with the most time I have"
4.5/5
What do you like best about CCleaner?

I think this is the program that I have used the most and with the most time I have. CCleaner is indispensable for my day to day. I use it because it has helped me keep my computer clean of old and unnecessary files and it also helps me to have a better login. Using this program my computer is in better condition. This program has a free version and another one that pays. Both are very good, but the paid version, as always, gives you access to more and better options. Review collected by and hosted on G2.com.

What do you dislike about CCleaner?

Sometimes I feel that this program is updated a lot and very fast. I understand this about updates, but it's a bit annoying that they are constant. And I really haven't noticed changes between one update and another. I guess there must be, but I haven't noticed them. Like this program is excellent and I really like the service it offers Review collected by and hosted on G2.com.
