Or am I missing the point?
I uninstall a piece of software with either the programs own-, windows- or jv16PT-uninstaller and after that I finish with Registry Cleaner with the already mentioned setting.
Before I can answer you question - I have to know what you are doing after you "finish with Registry Cleaner with the already mentioned setting"
I guess you select all and hit the button "Fix" - is that right?
