Microsoft Office

Microsoft Office is a suite of productivity programs created or purchased by Microsoft and developed for Microsoft Windows, and Apple Computer's Mac OS and Mac OS X operating systems. The newest version of Microsoft Office is 2007 which was released at the same time as Windows Vista (on January 30, 2007). Office 2007 introduces a new file format which is, of course, incompatible with previous versions of Microsoft office. Microsoft Office comes in several editions, with additional programs in the bigger editions (at higher cost).
