I can't recall having a registry cleaner with an exclusion list external/third party or otherwise.
The fact is the external list isn't installed by default so there is no 3rd party exclusion list, you have to download it but first you have to register on that forum to be able to get it.
Which is exactly why I said regseeker isn't a novice tool to be played with as a toy, you can do serious damage with an overzealous approach to cleaning the registry.
Also lets not lose sight of what the exclusion list does should anyone choose to use it, it stops you removing things which might harm the system, so it isn't taking decisions on which is safe to remove it isn't taking any decision on removal but the opposite what shouldn't be removed. RegSeeker doesn't make autonomous removal decisions, like HJT is just presents the user with a list according to their settings, the user takes the decisions on what to remove.
