On Monday, Microsoft updated the four-month-old Beta 1 version of Microsoft Office 2007 with a "Technical Refresh" version. Office has shed the preliminary name "Microsoft Office 12" for its final name, Microsoft Office 2007, and sports an improved version of the new ribbon interface . Among the new changes to the interface is the new Office Button, two new themes, a small Quick Access toolbar, and new, highly-legible default fonts named Calibri and Cambria.
