This command delete over 2GB off useless download of windows update that are already instaled on windows
Often suggested but it's a no go. These may seem useless to you, but removing them can break future windows updates.
what windows-version do you have?
w8.1 seems to be different.
in download i have only a few kb
and the hole softwaredsitribution have 130 mb...
I try on W8.1 and W10 i will report if i have future problem,
It won't break anything and will normally clear 700-1.2GB if not more on average pc.
Windows update which runs more frequently (daily or actually constantly) than someone decides to run ccleaner (or pro should be smart and ether not clear anything in that directory older than x months -- dates are for something; or clear less frequently like once a month -- not on or near release tuesday or whenever etc using pro thinking). Pro cleaner that is automated can be programmed to work with windows update or if not then around it. Meanwhile the non-pro can just screw the directory every time.
