CCleaner Utilities listing utilities no longer installed AND not in Registry nor Add/Remove Programs.
Example, lists Acronis True Image which I uninstalled several years ago.
ALSO: Lests EVERY version of PerfectDisk I have ever had, when the Add/Remove Programs ONLY lists the current version (PerfectDisk 12).
WHY
The right-click listed item context-menu needs a [Remove from list] option
