This appears to a rebrand of System Mechanic, which includes the features (such as the registry cleaner) which were omitted in Norton Utilities Premium.
yeah, more vendors want some slice of the cake when people try to break their operating system "we break your system better than others"
It won't break anything as, for example, it won't delete any valid registry keys, but is generally not needed.
no cleaner will delete legite trees or values, but in windows exists trees and values which dont have a valid end nor seem to have any usage. but windows will use those, deleting those will windows make misbehave. in special those are clsid and/or TypeLib. no one cares about not valid (temporary) values for windows update or missing path/files - any cleaner will find those, but will fail on the first ones. no cleaner is able to know about some trees or files if man has not programmed it. the exception list might long, but not complete. thats why windows always struggle on such cleaners. and people trust this crap. i dont not use such cleaners (although some of them are in my collections) but at least any of my current windows is running more worse or good or faster after cleaning, thats a myth. and someone told me that windows 10 has its own cleaning routing for temporary files, time is user set (default seems to be daily). and for the privacy switches - yes, they can kill a windows, my own experience last month. i dont know if such programs have a warning banner but they should have, the hint about creating a system restore point is waste of time, system restore is not reliable and can break windows really down to blue screens on booting. i should get some popcorn and coke
