As some of our club members, over the years, have expressed they use the popular software “CCleaner” . . . . here is a “Caveat Emptor” . . . .

The MS-Windows centralized “registry” has long been problematic insofar as OS stability and other issues (e.g., design weakness . . . “Single Point of Failure”).
Note that Android, IoS, Linux, Unix and MacOS’s use simple text files to do the job of a single registry (more flexibility and control).
