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. But the best part is that it's fast (normally taking less than a second to run) and FREE!
Starting with the version 4.18, CCleaner enables you to set up automatic monitoring and cleaning for Internet browsers and your PC in general. For example, every time you close an Internet browser, CCleaner can perform an automatic clean of browser files and settings, or it can ask you if you want to run a clean. Similarly, CCleaner can monitor your PC and, every so often, detect whether it will benefit from a clean and either clean it automatically, or ask you if you want to run a clean. When you enable automatic monitoring, CCleaner will continue to run in the background and you’ll see an icon in the system tray. Do not close this icon or you will disable automatic monitoring and cleaning.
Cleans the following:
- Internet Explorer
- Google Chrome
- Windows - Recycle Bin, Recent Documents, Temporary files and Log files.
- Registry cleaner
- Third-party applications
What's new in CCleaner 5.0 Beta:
After months of design, development and testing we are very excited to announce that CCleaner v5.0 is available to download in Beta! CCleaner v5.0 sees a change with a redesigned, modern interface. The current interface you know and love has remained largely the same since its first release almost 10 years ago, so we decided it was time to give it a fresh new look!
Our design team have worked hard to bring CCleaner up-to-date while making sure it still felt like the same tool that our hundreds of millions of users love. We are extremely happy with the result, and we hope you are too!
For advanced users we have a beta version of CCleaner v5 available for you to download. (We don't recommend using this outside of test environments. This build includes just the interface change. The other features will be coming over the next week, with a final release build at the end of the month.
