It doesn't list any products past NT4 or IE5, when in fact everything after NT4 and IE5 is still vulnerable, including a fully patched XP and IE6. I tested the registry entry mentioned in that article and it has no effect on XP/IE6. I'm not convinced they are even trying to address the same issue with that particular 'fix'.
