I really do not understand this. How do I address this?

Not quite getting the purpose and/or question meant with this topic.

I did however see your other post today and you might want to make a note that we're not Microsoft Support calling from Ivory Coast with an Indian accent, so we can't actually look onto your system to figure out ourselves what your problem might be.
