CCleaner is a freeware system optimization, privacy and cleaning tool. It removes unused files from your system allowing Windows to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history. Additionally it contains a fully featured registry cleaner.

Nowadays, cookies, temporary files, and various other means of tracking your Web footprint are par for the course. Some of these trackers are useful, while others can be potentially intrusive. Thankfully, there are myriad freeware cleaners out there that help keep your system in check. CCleaner is one of the better ones for its ease of use and powerful cleaning capabilities.

Trusted by millions and critically acclaimed. There’s a reason why the app is the world’s favorite PC optimization tool. Easy to use, one-click cleaning so beginners can optimize their computers in seconds and packed with advanced features for power users.

Faster Computer
Is your computer running slow? As it gets older it collects unused files and settings which take up hard drive space making it slower and slower. CCleaner 2020 latest cleans up these files and makes it faster instantly.

Safer Browsing
Advertisers and websites track your behavior online with cookies that stay on your computer. It erases your browser search history and cookies so any internet browsing you do stays confidential and your identity remains anonymous.

Fewer Errors & Crashes
Over time your registry can become cluttered with errors and broken settings which lead to crashes. C Cleaner’s patented registry cleaner clears out this clutter to make your PC more stable.

Quicker Startup
Many programs run silently in the background when you start up your computer.

We get the feeling that CCleaner has looked the same for the last decade but, either way, it’s pretty easy on the eye. While not particularly modern, it looks ok and is easy to find your way around. A large central area is where all the cleaning takes place, and along the left-hand side, you’ll see your program options, settings, and the option to upgrade.

CCleaner’s simple and intuitive layout will appeal to users of all skill levels. Its four features — Cleaner, Registry, Tools, and Options — are prominently displayed on the left side of the window. We started with the Cleaner first, which breaks down your cleaning options into two tabs: Windows and Applications. The program works by first analyzing your system and then running the cleaner itself. By selecting the appropriate check boxes, we were able to clean our temporary Internet files, cookies, history, and cache in both Internet Explorer and Firefox at the same time, as well as empty our Recycle Bin and rid our computer of Windows log files. The Registry feature acts in the same fashion, letting you check off on the options you’d like to scan for issues. In less than 30 seconds, the program had scanned and displayed a long list of invalid entries that we could then opt to fix or leave alone by unchecking the boxes. In less time than it took to scan, the program fixed the issues we had selected. One note: We did have to run the Registry cleaner three times in a row before it came back with no issues found; each time it came back with fewer and fewer invalid entries. Using the Tools feature, we were able to manage our startup programs and successfully uninstall programs. We especially liked that CCleaner lets you manage your cookies so that you don’t delete ones that are useful when browsing the Web. As with all Registry cleaners, we recommend that you proceed with caution before fixing or deleting any files. CCleaner does offer an online help feature, but for basic cleaning, you probably won’t need it.

CCleaner is an app that’s been around for a while and has lasted the distance despite rumors flying around. That says something and we find, for the most part, if you understand what it does and what you need to be careful of, that it’s a pretty solid app. That said, it’s not a completely necessary app.

CCleaner has three ways to optimizes, cleans, protects, and speeds up your PC:

  • Easy Clean
  • Registry scanning
  • Tools


Easy Clean is likely to be the part of CCleaner you’re most familiar with. It scans for trackers and junk, among which it lists the recycle bin and assorted temporary files. It’s satisfying to watch the app ‘scan’ and present you with a list, even if most of us aren’t really sure what we’re cleaning.

The registry scan is the part most users are scared of. CCleaner presents you with a list of registry items that are broken, missing, unused, or obsolete. It then offers to ‘fix’them but recommends that you back them up in case something changes for the worse.

Finally, CCleaner’s assorted tools are handy little utilities. There’s an uninstaller, updater, start-up menu manager, browser manager, disk analyzer, duplicate finder, system restore, and a drive wiper.

By default, the project opts you in for installing desktop and Start menu shortcuts, as well as adding run and open options in your Context menu. It also opts you in for installing Google Chrome and making it your default browser, so you’ll have to uncheck the boxes to opt out. CCleaner installs and uninstalls without leaving any files or folders behind.

Is it dangerous?

That question is a bit dramatic. We don’t think CCleaner is dangerous but it does give you access to some tools which, used wrongly, could have a negative effect on your computer – especially the registry cleaner.

CCleaner was designed from the ground to be safe and secure to use. It has multiple levels of checks in place to ensure that it cannot delete any useful information or documents you may still need.
