CCleaner is a utility from Piriform that finds and removes junk files and errors on Windows PCs (including Windows 10). With a few clicks, CCleaner helps recover disk space and makes your PC faster and more efficient. CCleaner is also available for Mac and Android.
A great optimization kit
Cleaning is the main function of CCleaner. With a quick scan, it detects unnecessary Windows files and applications you have installed and helps you to remove them simply and effectively.
The CCleaner Registry section is devoted to verifying the integrity of Windows Registry, the file containing the system configuration. CCleaner scans the registry for more than a dozen types of errors and provides the ability to save a backup copy before carrying out a repair.
CCleaner's tool menu contains more specific utilities, such as a quick uninstaller, a list of the programs that start when you launch Windows, and a restore point manager.
A classic interface
To clean files, simply click on the Scan button and let CCleaner discover how much waste has accumulated. Another click on the Run button and it will clean your disk instantly.
CCleaner scanner can be customized to find and remove only what you want it to. The process involves checkboxes, so it can take a little effort at times.
Registry Cleaner works in a very similar manner, and also shows the types of errors that it finds. It is quite technical information, but if something goes wrong CCleaner offers a restoration to a previous backup.
Other tools are equally simple but provide little information. Though, in truth, this minimalism is appreciated - especially when compared with other cleaners' busy interfaces.
Depends on your situation
The utility and effectiveness of CCleaner depend on what you need. To maintain privacy it is very powerful, but its scanning is not the fastest.
The registry cleaning only helps in rare cases and is an operation of limited usefulness in recent versions of Windows.
The removal tools are basic but work well, though they can occasionally display incorrect data and obsolete entries that could just as easily be deleted by hand.
In a category as challenged as cleaners, in which it is difficult to find honest and effective programs, CCleaner stands out for its simplicity and effectiveness. Piriform also offers CCleaner Professional and CCleaner Portable. If you are looking for other free alternatives, we recommend you to download Glary Utilities or Clean Master for PC.
