I'm using CC free version. I've tried the regedits to '0' for the software updater entries and initially that worked and the software updater didn't show up. Now though if I run ccleaner it instantly resets those entries to '1' and the software updater is back, even though useless in the free version. I don't find it a real problem though.
One funny thing I'm surprised no-one has mentioned is that the Piriform program Speccy shows up in the up to date program list as having "Unknown publisher".
