    What happened to 'Slim' builds? Now just main larger install or similar size portable. I'm still using 5.11.5408 Slim build(the last slim build). I may have to find something else.

    Please ignore fredreed's comment, because you can't call it a review. I have used this on every PC for years. It is an exceptionally good cleaner offering great control over what it cleans. Equally it can be used in a more simple mode for those with limited knowledge. Not once has it caused a problem for me, and it seems that 99% of the other reviewers would concur with my findings.

    Continues to be my favorite cleaner. Have put it on thousands of PC's over the years without ever having a problem from it.

    CCleaner is still the worst product on the market today and If you people who are obviously a bunch of idiots think that CCleaner is a good program you must be very stupid. CCleaner is the most terrible product out there today. It's a ripoff and you people are being taken in by It.Stop wasting your money on this garbage.

    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 but Yahoo! toolbar. It's recommended that you should install the Slim version.

    Not only that, but it tries to install on your computer! :-O

    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?
