Microsoft Office 2003
Microsoft Office 2003 was released in October 2003. Two betas were released. A new Office logo was debuted, as well as two new applications: InfoPath and OneNote. OneNote is a note-taking and organizing application for text, handwritten notes or diagrams, recorded audio and graphics, and InfoPath is an application for designing, distributing, filling and submitting electronic forms containing structured data. Office 2003 was the first version to use Windows XP style icons, visual styles and colors.
Office 2003 runs only on NT-based versions of Windows; it is not supported on Windows 98, Windows Me, or Windows NT 4.0. It is the last version of Office compatible with Windows 2000, as Office 2007 requires Windows XP SP2 or newer. It is listed as being "Not Compatible" with Windows 8. Service Pack 1 for Office 2003 was released on July 27, 2004, Service Pack 2 was released on September 27, 2005, and Service Pack 3 was released on September 17, 2007. The last cumulative update for Office 2003, Service Pack 3 resolved several compatibility and stability issues with Windows Vista and later operating systems. Mainstream support for Office 2003 ended April 14, 2009, and extended support April 8, 2014.

Office 2003 was the last version of Microsoft Office to include fully customizable toolbars and menus for all of its applications, the Office Assistant, the ability to slipstream service packs into the original setup files, Office Web Components, and the Save My Settings Wizard, which allowed users to choose whether to keep a locally cached copy of installation source files and several utility resource kit tools. It was also the last Office version to support Windows 2000. A new picture organizer with basic editing features, called Microsoft Office Picture Manager, was included.
Only basic clipart and templates were included on the disc media, with most content hosted online and downloadable from within the Office application. Microsoft advertised Office Online as a major Office 2003 feature "outside the box".Office Online provides how-to articles, tips, training courses, templates, clip art, stock photos and media and downloads (including Microsoft and third-party extensibility add-ins for Microsoft Office programs).
Office 2003 features broad XML integration (designing customized XML schemas, importing and transforming XML data) throughout resulting in a far more data-centric model (instead of a document-based one). The MSXML 5 library was introduced specifically for Office's XML integration. Office 2003 also has SharePoint integration to facilitate data exchange, collaborated workflow, and publishing. InfoPath 2003 was introduced for collecting data in XML-based forms and templates based on information from databases.
