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.

CCleaner Professional is the most powerful version of Piriform's celebrated PC cleaner. It makes it easy to speed up a slow computer and keep your activity private — automatically and in the background.

These are some of the features you get with CCleaner Professional:

Automatic Cleaning

Regularly cleans junk files to keep your computer running smoothly

Automatic Privacy Protection

Clears history and cookies when you're not using your web browser

Automatic Updates

Windows and browsers constantly evolve. CCleaner updates once a month to stay on top!
