The Very Helpful CCleaner
CCLEANER IS ONE OF most valuable pieces of freeware, used weekly to keep my hard drive churning with enough free space to render video without overheating. It's free, so I didn't expect a sweet user interface and wasn't disappointed because it launches straight away and cleans as much as you trust. If you share your laptop or desktop, you should use CCleaner to wipe away your tracks from Internet Explorer, Firefox, Opera, Google Chrome and from various Windows system areas. It also snags and zaps artefacts from Spybot and WinZip. Its Registry-cleaning utility surprises some of my friends because it scans for invalid entries before removing them. More than anything else, I can trust CCleaner to clean up without destroying valuable stuff that I need. I've used it for more than a year and in that time, it's kept me up and running without the need for a scratch installation of my Windows operating system.
You can download CCleaner from CNET.
