Microsoft Office 2003 Service Pack 3 (also called Office 2003 SP3 or Office 11 SP3) provides the latest updates to Microsoft Office 2003. Service Pack 3 contains significant security enhancements and stability and performance improvements. Some of the fixes included with SP3 have been previously released as separate updates. This service pack combines them into one integrated package, and it includes a number of other changes designed to improve the reliability and performance of Office 2003 programs.
Note: All fixes from SP1 and SP2 are included with SP3, so you only need SP3 to update Office. But don’t forget there may be new patches released after SP3. Office 2003 Service Pack 3 was released in late September 2007.
