CCleaner (or Crap Cleaner) is an award-winning and popular system optimization, privacy and cleaning utility, developed by Piriform. It a multifunction small and effective tool designed to protect your privacy online and makes your PC computer faster and more secure.

It allows you to clean junk data that accumulates over time from your system - to free up valuable hard disk space, and to clean traces of your web online activities such as your internet browser history allowing you to be a more confident Internet user and less susceptible to identity theft.

Moreover, Piriform's cleaning tool offers a fully featured registry cleaner (remove unneeded entries in the Windows Registry), uninstaller tool (help remove unneeded programs), startup manager (select which programs start with Windows), disk analyzer, and disk wiper that allows you to wipe the free areas of your hard disk so that deleted files can never be recovered. It's an advanced yet easy to use tool for both beginners and advanced users.

CCleaner uses internally-stored settings (.INI) files to determine which Windows settings and installed applications to clean, and how to clean them. You can modify these .INI files by creating replacement external ones and placing them in CCleaner's installation folder. .INI files are in plain text, so you can edit them with Notepad or manipulate them with scripting programs.
