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.
Outdated apps are a security risk.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.
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 As it gets older it collects unused files, settings, and out-of-date software drivers which can make it slower and slower.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.
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.
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 Out-of-date software drivers can cause similar issues too.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cleaner clears out this clutter to make your PC more stable, and Driver Updater helps you keep on top any unruly, out-of-date drivers.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.
