..."Microsoft came out with latest service pack for XP, four years
after SP2 was released. XP itself is very stabile system with SP2 installed,
so SP3 is considered as not so innovative like it was SP2. The essence of
this service pack is to bring all patches for XP that are released until

new additions that should provide better network collaboration, easier
administration etc. "...
