    Shailesh, your article was very helpful. I particularly appreciate the screenshots, since I need visuals to get a good understanding. It has always been difficult for me to determine what files are unwanted. I have a fear of deleting a core system file, so I tend to rely on registry cleaning software for that. Seems like this could be a disaster if the wrong file got deleted.
