I was hoping (praying) that someone would be able to guide me as to how I can mend class not registered on many of my directory file. In windows explorer even my right clicking on my home screen widow and trying to personalize will give me a class not registered.. Is there a tutorial or can someone guide me as to what I need to do.. Can I re-register only say windows explorer as that program seems to to be the culprit Help please
