CCleaner (formerly Crap Cleaner) is a freeware system optimization and privacy tool. It removes unused and temporary files from your system - allowing Windows to run faster, more efficiently and giving you more hard disk space. The best part is that it's fast! (normally taking less than a second to run) and Free.
This new release of our flagship product CCleaner adds various new features, speed improvements and bug fixes.
It is always nice to donate to free software vendors and I can vouch for Piriform Ltd. CCleaner is certainly a time saver and essential to any Windows OS!
