Why is CCleaner the world's most popular and highly acclaimed PC optimization tool trusted by millions of users?

The reason is that it is easy to use and offers one-click cleanup, so even beginners can optimize their computers in seconds. It also includes many advanced features for more advanced users.

Is your computer slow?

Over time, unused files, settings and outdated software drivers accumulate and increasingly slow down your computer. CCleaner cleans up these files and updates software drivers to speed up your PC.

Surf more securely

Advertisers and many websites log your online behavior using cookies that are stored on your computer. CCleaner deletes your browser's search history and cookies, keeping your Internet activity private and not revealing your identity.

Fewer errors and crashes

Over time, errors and corrupted settings accumulate in your registry, causing crashes. Outdated software drivers can cause similar problems. CCleaner's patented Registry Cleaner cleans up this junk so your PC runs more stably, and Driver Updater helps you bring outdated drivers back up to date.

Manage Notifications

We've made it easier to turn off a Smart Cleaning notification if you don't find it helpful.

Keep your drivers up to date

CCleaner now automatically scans for new drivers once a week.

To reduce confusion caused by version numbering from different vendors, drivers now display the release date instead of the version (version information is still on the Driver Details screen)

Minor accessibility and usability improvements

Getting started with CCleaner

We've added a short introduction to the product to give newcomers a little guidance

Smoother CCleaner experience

We fixed a crash that occurred when trying to clean Firefox installed with a Windows user account that is not an administrator.

We added a warning if you try to register the paid product while not logged in with an administrator account

System Requirements

Runs on Microsoft Windows 10, 8.1, and 7. Both 32-bit and 64-bit versions.

Faster startup

Many programs run unobtrusively in the background when you start your computer. With CCleaner, you can get to work or play faster by disabling programs you don't need.
