I had to call MS for help with my Office Home and Student 2010. While we were waiting for the connection to my computer I asked him about W 8 and for what it is worth here is what he said. It is more of a special edition for use by laptop and tablets and desktops. He said the next OS after that will have the start button and reg OS like we usually get. I really hope that is true.
In case anyone else has the same problem I had with office home and student 2010 which was reverting back to trial version. He uninstalled the trial version and it should be okay now. I had already uninstalled the starter version, but there was more to it than that. He also helped get rid those tiny black zig zag lines in word that I couldn't get rid off. While I watched him do that I saw a place to change the 1.5 spacing to single spacing. In was in the drop down paragraph section.
