For the past week or two, I keep getting the Windows automatic update wizard telling me I need to install a high priority security update for Microsoft XML Core Services 4.0 Service Pack 2 (KB954430). I have installed this multiple times in several different ways. I have installed it through the wizard as an express install and as a custom install. But it keeps popping up telling me I need to install it. I also installed it going to the actual Windows update website and doing it through there. But I still haven't had any luck. So this is becoming pretty annoying. Does anybody know how to fix this or check to see if its installed? Could it be my anti-virus? I am currently using Bit-Defender 2009.
