CCleaner is a freeware system optimization, privacy and cleaning tool. It removes unused files from your system - allowing Windows to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history. Additionally it contains a fully featured registry cleaner. But the best part is that it's fast (normally taking less than a second to run) and contains NO Spyware or Adware.

    This is an excellent piece of software, I have used it for many years and not once had an issue. I can't help but think of the saying workman and tools in respect of those who have rated it so low.

    Music4forever CCleaner is the worst program out today. If you install this program then you will destroy your PC. This program should be banned from being sold on the internet. This program is nothing but junk.

    best in it's class, to answer a few comments below, if you don't want the monitor to run in the background disable it, under tools start up. For the guy that had his PC explode, my guess, it would have been the registry cleaner. Their is no all in wonder registry tool cleaner/optimizer that does not pose a risk. They do give you a option to back it up before changes are made.

    You don't have to have this program running in the background anymore than you ever have unless you want it that way, Still the best basic PC cleanup program by a fair margin & still free.

    Edit: @fredreed - I appreciate your point of view of this program & your personal bad experience with it. However I've used it from the very beginning & installed it on dozens of PC's without any problems. As mentioned elsewhere perhaps the registry cleaner element caused your problem? Personally I'm not a fan of automated registry cleaning & prefer manual removal of leftover programs - But it's pointless for this continued argument on here. I use Ccleaner & find it useful, however I fully accept your point of view of it also.

    As always everyone should always ideally have saved images of C:\ & backups of other data at all times as all cleanup programs (and life) have the potential to cause problems... Paul

    I keep an old version before it got the systray icon and background running service.

    Too bad this program went to hog software fringes.

    I stand correcfed. It IS cleaning the Flash cookies -- it's leaving a "settings" file, which also carries an ".SOL" extension, which I thought was a cookie

    How about adding an option to remove FLASH COOKIES?

    I haven't used this product in a while and when my PC gets full, I'll use it to clean clean it out.

    CCleaner doesn't install ask.com but Yahoo! toolbar. It's recommended that you should install the Slim version.

    I hear you! I had to reinstall my OS because I used the registry cleaner! With such small files being installed into the registry, just leave it alone. There is NO WAY that any registry cleaner could possibly know all of the file names that program writers make up and install. BAD IDEA!

    Everyone here seems to have lots of love for this program, but today it killed my wife's laptops registry. I think it would of great help if the registry list of "problems" had a collumn with the origin of the file, so you can see if it is a valid entry, or something that really should be deleted. because lets face it, does anyone really know exactly what every dll file does- by name?
    How do we make an informed choice on which to delete or not delete?
