hi there,
i had Windows 7 64 bit with CCleaner v2.27.1070 running and there are so many options being disabled, are they done in purposed or bugs?
P/S: attached screenshot.
They are disabled by default for the sake of safety, ie those are the options that can cause users a problem (not that it makes much difference as new users nearly always tick everything without bothering to read up on what each option does), or are options that simply don't need to be run with every clean.
