Windows 8.1, Norton Utilities 16, configured to do daily optimization, reports "Your system has been cleaned" and "Registry issues repaired: 127". This report repeats nightly, with the number of issues allegedly repaired ranging from 125 to 129. If I continue to the "1 click optimization" the suggested next step is "Clean Registry." Clicking this results eventually in a report that some small number of issues have been repaired but many remain unrepaired (totaling about 125-129.) The next night I get the same claim of 127 registry items repaired.
