XP shares the same kernel as Server 2003. I checked a few older patches and it's the same. IE 6 critical patch from October isn't available for XP, we both know IE 6 is in XP.
*I'm not trying to convince you to upgrade. I just want you to be aware that XP will soon be pretty risky to use if it isn't already.
