Why is CCleaner the world’s most popular and highly regarded PC optimization tool, trusted by millions of users?
The reason is that it’s easy to use and offers one-click cleaning, so even beginners can optimize their computer in seconds. It also includes many advanced features for power users.
Is your computer slow?
Over time, unused files, settings, and outdated software drivers accumulate and increasingly slow down your computer. CCleaner cleans these files and updates software drivers to speed up your PC.
Surf safely
Advertisers and many websites track your online behavior using cookies stored on your computer. CCleaner deletes your browsing history and cookies, protecting the privacy of your online activity and preventing your identity from being revealed.
Fewer errors and breakdowns
Over time, errors and corrupted settings accumulate in your registry, causing crashes. Outdated software drivers can cause similar problems. CCleaner’s patented registry cleaner removes this junk to keep your PC running more stably, and Driver Updater helps you update outdated drivers.
Manage notifications
We’ve made it easier to disable a smart cleaning notification if you don’t find it useful.
Keep your drivers up to date
CCleaner now automatically checks for new drivers once a week.
To reduce confusion caused by different manufacturers’ version numbering, drivers now display the release date instead of the version (version information is still available in the Driver Details screen).
Minor improvements to accessibility and usability
Start with CCleaner
We’ve added a short product introduction to give newcomers some guidance.
A smoother CCleaner experience
We fixed a bug that occurred when trying to clean up Firefox installed with a Windows user account that is not an administrator.
We’ve added a warning if you try to register the paid product without being logged in with an administrator account.
System requirements
Works under Microsoft Windows 11, 10, 8.1 and 7, in 32-bit and 64-bit versions.
A faster start
Many programs run silently 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.
