This is the software publisher's description.

CSC allows users of all experience levels to thoroughly clean their systems of damaging and/or wasteful files, boost system performance and unlock the full power of any Windows XP or Vista computer.

Comodo System Cleaner contains a fully featured Registry Cleaner that removes corrupt and obsolete registry entries - often the cause of system instability and slow down. The Disk Clean utility allows you to free up disk space and improve system performance by thoroughly removing temp, archive, duplicate and other useless files. Comodo Privacy Cleaner keeps your personal details safe and sound by comprehensively clearing all traces of private data from Internet browsers, Instant Messenger and Windows software.

What's more, CSC is the safest Registry and System cleaning utility available today. The unique 'Registry Protection' and 'Safe Delete' features will automatically recover any files deleted in error and restore your system to its previous state should any problems occur.

Through its single interface, you can fine tune virtually every aspect of Windows behaviour, functionality and performance. You get fingertip access to important controls and settings that are either not available or are very difficult to find in Windows XP or Vista - without the need to manually navigate through multiple Windows menus.

CSC also boasts numerous additional utilities to safeguard your privacy and security such as the hash value calculation tool. Innovative new utilities are constantly in development so this software will become even better over time.

Note that this is the 32-bit version.
