Win10 native "disk cleanup" vs. CCleaner: temp files discrepancy

    Windows disk cleanup tends to be very conservative in what temp files it will remove. Specifically it will only delete files beyond a certain age. The reason being that some applications have different ideas about what "temporary" means and may want to keep these files longer than you may think. Applications create temporary files and can use them for any purpose desired. Their removal could have unpredictable results.

    Windows disk cleanup is used by novices who have no idea of the possible implications. They need an extra level of protection. If an individual installs a more aggressive cleaner they will be responsible for any problems it may cause.

    By default Ccleaner does not remove any temporary files younger than 24 hours.

    Yep, I am used to seeing a discrepancy between Windows utility and CCleaner -- just not such a HUGE difference.
    That was the impetus behind my inquiry.

    I'll create a restore point and make sure everything is backed up (yes, a system image, too!) and then will take the plunge with CCleaner.
    Over many years on many platforms, I only recall one bad incident after cleaning temp files with it.
    Once burned, twice shy, I suppose.

    I just don't want to brick my brand new, spanking Win10 box that I've just spent 10 days getting all buffed and tuned.
