A family of Microsoft word processing software products for creating web, email, and print documents.
You're seeing this because you have the Word window sized extremely wide on a high-resolution 1680x1050 display. If you want to see just one page in the center of the Word window at 100% zoom, drag
the right edge of the window to the left so it's nearly the same width as the ribbon.
Word makes its decision of how many pages to display on the basis of the current width of the page (as set by the zoom factor) compared to the current width of the client window (the blue space). If
it can fit two pages, then it will show two pages -- there is no way to tell it not to. Because you want a specific zoom (100%), the only factor you can adjust is the window width.
