OnePiece checked ClassIDs present in ie7.addreg (and in Vista, this is the reason because unpresent entries in IE7 update.inf were added) so he removed them in ie.inf. And what you wrote "cosmetic" version is correct "6,0,2900,5512" because that is OS version and not IE version. Your work was amazing too and OnePiece and I like your iepid and probably it will be added in next addon's versions. OnePiece and kontini
