Microsoft expects last week's Office XP Service Pack 1 (SP1) release to usher in a new era of corporate adoptions of the product because many organizations wait for the first consolidated update package before upgrading. In this case, that expectation is probably warranted. In addition to focusing on the three general areas of security, stability, and performance, Office XP SP1 includes several Windows XP-specific performance improvements that let the two systems work more efficiently together. I spoke with Office XP Product Manager Nicole von Kaenel about the changes in SP1.
