You are at it again, when are you going to learn, this has nothing to do with the original IE 0day post by Aysn you quoted and my follow up.
Vista is also effected, but I guess you didn't read all of the information Asyn posted or you would have done as I did and post the Mitigating Factors that limit the potential of this 0day exploit; rather than trying to deflect security notices on IE to other areas as is very common for you.
I don't really care if people are using win7 64bit (though some win7 users are vulnerable if they aren't using IE9 beta) and or IE 9 beta as they aren't mentioned in the 0day exploit that was posted.
