NEW! DRIVER UPDATER
NEW Driver Updater
CCleaner’s new Driver Updater improves things like your PC’s visuals, sound, and internet connectivity while preventing software bugs, hardware problems, and crashes.
PC Health Check
CCleaner’s new Health Check analyzes your PC and recommends quick fixes, then automatically tunes and updates it so it starts and runs faster, and is more secure.
1-Click Updates All Your Software
Outdated apps are a security risk. Old software can have vulnerabilities, which are quickly discovered and shared amongst cybercriminals. CCleaner updates your software automatically to close security holes before they can be found.
Award-winning PC Optimization
Trusted by millions and critically acclaimed, there’s a reason why CCleaner is the world’s favorite PC optimization tool! Easy to use, one-click cleaning so beginners can optimize their computers in seconds. Plus, it’s packed with advanced features for power users.
Is your computer running slow? As it gets older it collects unused files, settings, and out-of-date software drivers which can make it slower and slower. CCleaner cleans up these files and updates software drivers, making your PC faster.

Fewer Errors & Crashes
Over time your registry can become cluttered with errors and broken settings which lead to crashes. Out-of-date software drivers can cause similar issues too. CCleaner’s patented registry cleaner clears out this clutter to make your PC more stable, and Driver Updater helps you keep on top of any unruly, out-of-date drivers.
Many programs run silently in the background when you start up your computer. CCleaner helps you get to work or play faster by letting you disable unneeded programs.
