It was developed by Piriform and is designed for Microsoft Windows. CCleaner is freeware, though Piriform accepts donations through its website to develop the company's programs further. CCleaner is available in 37 different languages, with more to be added. Piriform claims on the homepage that as of 23rd December 2009 CCleaner had over 375 million downloads.[1]

[edit] Features
CCleaner allows the user to remove unused temporary files from Internet browsers and other supported applications along with browsing history, cookies, recycle bin, and AutoComplete form history.[2] It allows for the cleaning of the recycle bin, memory dumps, file fragments, log files, system caches, application data, and various other data. The program also includes a Registry Cleaner to locate and correct problems in the Windows Registry such as missing shared DLLs, unused file extensions and application paths.
CCleaner supports the cleaning of temporary and unneeded files from certain programs, including Firefox, Opera, Internet Explorer, Safari, Google Chrome, Foxit Reader, Microsoft Office (97, XP, 2003, 2007), Nero Burning ROM, Java, Windows Live Messenger, ZoneAlarm, Flash Player, QuickTime, VirtualDub, Windows Media Player, 7-Zip, Avira AntiVir, Spybot - Search & Destroy, Windows Registry Editor, eMule, KaZaA, Google Toolbar, Netscape, Adobe Acrobat, WinRAR, WinAce, WinZip, and many other applications.
CCleaner assists in the uninstallation process by allowing users to uninstall programs from CCleaner itself. In addition, CCleaner also allows the alteration of start-up programs, similar to the Microsoft Windows MSConfig Utility. Users can disable several start-up programs to free up processor speed at start-up. As of version 2.13.8, CCleaner also allows users to delete System Restore Points.
[edit] Version 2.0
CCleaner 2.0 is completely rebuilt in C++[3] and portable and compatible with all 64-bit versions of Windows XP, Windows Vista and Windows 7. The scanning process was also rewritten in C++, which enabled faster analyzing and cleaning. Its design also makes it capable of being installed onto a USB flash drive, which ensures portability.
[edit] Old Prefetch Data
It is not recommended to delete files from the Windows Prefetch folder by ticking the box "Old Prefetch data" in the Advanced section. Deleting prefetch files reduces performance; applications and Windows will load slower. Windows automatically cleans unused prefetch files.[4][5]
