easy cleaner was never really released for Vista or W7 and has not been updated in years. I also read one review that said the duplicate file finder can mess up your system if you allow it to delete duplicate files; there are very good reasons to have identical files in different folders. So if you choose to use it in W7 then you might look over the results but I wouldn't let it delete dup files.
vmars, autoruns has many tabs, could you post a screen shot of the full autoruns window showing what you say is duplicated?
