Word Up

I just installed MicroSoft Office 2007 on my computer. I had Office 2003 on my old computer and could not bring it to the new machine. I opened up Word tonight to do an outline and some notes...Good Grief!!!! Who's been messing with my word processing program? Where is everything I am used to? Who moved the buttons? Who decided this was a good idea? Who put all of that junk at the top of the page? Who made changing fonts more difficult? Who did this? Who, Who, Who?
