New! PC Health Check
What’s that?

New 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    Outdated apps are a security risk.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 cyber criminals. 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.

  • Faster Computer

    Is your computer running slow? As it gets older it collects unused files and settings which take up hard drive space making it slower and slower. CCleaner cleans up these files and makes it faster instantly.

  • Safer Browsing

    Advertisers and websites track your behavior online with cookies that stay on your computer. CCleaner erases your browser search history and cookies so any internet browsing you do stays confidential and your identity remains anonymous.

  • Fewer Errors & Crashes

    Over time your registry can become cluttered with errors and broken settings which lead to crashes. CCleaner’s patented registry cleaner clears out this clutter to make your PC more stable.

  • Quicker Startup

    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.
