Has anobody tried adding this hotfix (KB902400) to an Unattended XPSP2 install CD/DVD? In my case, it breaks up windows - badly (IE doesn't work, updates won't work etc). I understand your points about it "not being MS's fault if somebody has messed with their registry and/or ACL" and the hotfix then creates problems. As I see it, MS managed to release a BUNCH of hotfixes that work perfectly when slipstreamed into a XP SP2 media, this is the first to FAIL miserably. Oh well, maybe they'll release a new version of KB902400. Soon, I hope - I like to keep things neat, so even ONE hotfix that can't be applied into installation media is ONE too many for me!
