I have been using this program for 3 years and it has worked perfectly.
It is VERY easy to use, too.

Adorable program that does what thousands of other programs can do, but it looks snazzier, so I favor it.

I have used this software for two years, and it has been very good indeed. I always use backup with ccleaner, but have never found the need to use backup, so use the reg. cleaner with confidence.

Have used c cleaner for two years now and it is without doubt one of the most efficient cleaners and easy to use cleaners anywhere on the internet a user friendly interface and does not attempt to take control of your computer as many other pieces of software do

CCleaner is an excellent, powerful, freeware tool, but it is not a thorough as some alternatives (free and shareware or commercial). The first such product that I found and licensed was Tracks Eraser Pro, back in 2000, for which I purchased a lifetime license for $29.95 USD. Tracks Eraser Pro is much faster and more thorough than CCleaner, but when I last checked it is not compatible with Vista. Also, if you run CCleaner on a computer with multiple Windows accounts you may encounter problems with CCleaner not being able to clean certain directories, because those directories belong to other users: Each user will have to run CCleaner manually from her or his account, or you can log in as Administrator to run CCleaner on the entire PC for all accounts. (WARNING: If you have one account on your system, yours, and you run as administrator all of the time, any damage by a "cracker" or malicious software will have administrative/"root" privileges -- ensuring maximum damage to your OS and, with especially destructive "malware," destruction of most or all of your data...whereas running as a standard user restricts the power of malware and "crackers." CCleaner also will be unable to perform a thorough cleaning if you share a computer and every user insists upon being in the administrators user group -- but "cruft" on your hard drive is the least of your worries if every user's account gives "the dark side" the rights of the 'Administrator' account; multiple administrative accounts on one machine adds to your risk. I speak from experience, because I provide free support to 10 family members in the area who run Windows XP Home or Pro, have ignored my warnings about running as an administrator "because it is more convenient," and I am sick of rebuilding Windows XP installations and reinstalling all of the programs -- over and over.) Back to CCleaner.... I suggest enabling he setting to ignore temporary system files less than 48 hours old. Although CCleaner has a registry tool (with a backup feature), use it at your own risk. It takes a "sledgehammer" approach, although it is safe to delete registry entries for programs that you have uninstalled. Finally, do not set CCleaner, or any similar product, to run at startup or shutdown! When you install or uninstall many programs, the installation/removal process does not complete until after you reboot the system. The installer/uninstaller needs temporary files that it has created to finish the (un)installation, and you will corrupt the process -- which is especially nasty if you are installing a program -- by deleting these needed files. You can always use Task Scheduler to have CCleaner run a few minutes after Windows has loaded (a process that requires administrative privileges); just remember that CCleaner will display an error and abort its "cruft removal" if you are using a Web browser and do not close it. (It does not simply skip cleaning tempororary files in use by your browser, CCleaner aborts the entire cleaning process.)
