  1. I am ready to throw my new Windows10 computer off the roof.
    I can’t find any help anywhere.
    I see by your image that you made your W10 Mail box brown.
    How did you do that? I cannot get rid of the bright white reading pane.
    Also, I do not have the sun or moon icon like you do!
    Does this perhaps mean i have an old version or new version?
    I just bought it today.

    thank you so much.
    happy to pay you for your time if you can help me make my mailbox ALL brown like you have.
