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.

    Still dont like the new "look", but it is also still the best at what it does and it's free. 5 Stars as always

    ALL of my Network tools have the Crappiest UI's ever. Windows gray round the
    Edges & pale Background. Some are CMD apps, So no UI at all.
    These apps are some of the Best, & have served me well. A schmancy UI ain't
    making 1 Iota of difference.

    Read an earlier post of mine about CC/Index.dat
    If it does the Job, Then why bother about Looks..??

    I know our friend Mus4ever rates CCleaner "very highly", & Rightly So.
    CC does the Job Right, & I just happened along & Tested it with S/hidden
    Sys files...

    Guys..... Don't chalk CCleaner down Cozza the UI. It does far more Cleaning
    than Similar Apps. Listen to the 5* Reviewers, & I'm one of 'Em. (PROVEN 5*)

    1st time Users. Use caution when Deleting..!!

    I've installed this program on countless PC's over the years & recommended it to hundreds too & have yet to have a problem with it - I don't know what fredreed below problems are with CCleaner are but IMO it's the best program around of it's type including all pay for cleaners - I also use the winapp2 additions too & have no problems with using those also - Always 5 stars.

    Stat away from using this crap. ccleaner is the worst program ever to use> If you want to destroy your PC then go right ahead and use this garbage. But you have been warned.

    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?
