The only thing I can think of is that you are using the same basic batch to not only install updates, but also install something else, and that is what you don't want people to see. If that is true, then that secrecy implies something nefarious, and if I was one of your users I would be that much more curious and would trust you less in general. I also noted that you did not answer my previous questions. I can understand that you "want to learn, to learn, to learn", but what exactly are you wanting to learn and for what purpose? Cheers and Regards
