There really isnt much new in Microsofts Office XP Service Pack 1: Almost all of its fixes and updates have been available for at least a few months. In fact, SP1 probably wont change the mind of any business that wasnt sold on Office XP in the first place.
SP1 includes updates to most of the components in Office XP, and Microsoft claims that it will improve performance and stability. But, aside from the fact that removing bugs should improve performance and stability, I saw no noticeable differences after installing the service pack.
SP1 can be installed via the automatic update site at www.office.microsoft.com/productupdates. The complete 18MB file can be downloaded from www.office.microsoft.com/downloads/2002/oxpsp1. aspx.
Sites that installed Office XP on CD-ROM must have the Office XP CD in the drive to install the service pack.
