Running RegSupreme Pro ver 1.8.0.472 on XP Pro sp2. Been running RegSupreme for a few years through many versions on current PC and current OS install. When running Registry Cleaner In previous versions (any level of aggressiveness) It always came up with any number items to fix. I knew it was working because of that. This latest version turns up nothing... time after time, at any level of aggressiveness. Although I'd like to celebrate the cleanliness of my machine, in reality, There may be more to this that "doesn't" meet the eye. What can I do to see if RegSupreme is working? Perhaps add some sort of duplicate entry in the registry or something like that to test it's effectiveness? :?
