Office 2007 introduced a new graphical user interface called the Fluent User Interface which uses ribbons and an office start menu instead of menu bars and toolbars. Office 2007 requires Windows XP with Service Pack 2 or higher, Windows Server 2003 with Service Pack 1 or higher, Windows Vista or Windows 7. Office 2007 is the last version of Microsoft Office to support Windows XP Professional x64 Edition and the first version to officially work on Windows 8.
Office 2007 includes new applications and server-side tools, including Microsoft Groove, a collaboration and communication suite for smaller businesses, which was originally developed by Groove Networks before being acquired by Microsoft in 2005. Also included is Office SharePoint Server 2007, a major revision to the server platform for Office applications, which supports Excel Services, a client-server architecture for supporting Excel workbooks that are shared in real time between multiple machines, and are also viewable and editable through a web page.
