Microsoft has pushed back the release date for the second Windows XP service pack to the third quarter of 2004. SP2 was long expected to debut before the end of 2003
The possible implications of the move are far reaching. A yearlong delay gives Microsoft significant time to further its integration strategy with Windows XP – building more components directly into the operating system.

"It's possible that Microsoft is preparing a more substantive-than-usual service pack that would add new features to Windows XP or hybrids Media Center and Tablet PC," said Wilcox.

One such potential feature is Microsoft's PC Satisfaction package, currently in beta testing. PC Satisfaction extends the native functionality of Windows XP with services such as an enhanced firewall and virus scanner that give customers a better Windows experience out of the box.

Although Microsoft has not yet announced how it plans to issue PC Satisfaction in its final form, the company hinted that a new firewall would be enabled by default in the next Windows XP update.
