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.
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. CCleaner’s patented registry cleaner clears out this clutter to make your PC more stable.
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.
