I have ran into an odd problem today, I can't install any of todays winupdates as it says they haven't passed windows logo testing :/

Microsoft warns that installing this can cause certain websites to fail to load in IE. Make sure you read and understand the known issues before installing.

This is not a terribly useful update for the masses. This is why it is not critical. It is highly unlikely that you are using IPv6 and you should avoid installing superfluous protocols as, if you do not need them, they can only do harm. I am uncertain why Microsoft does not hide more updates as standalone packages or some "expert" feature. Those who need this will know and those who don't may only have the pleasure of a buggy IPv6 stack perhaps even interfering with their regular IPv4 install (speculating, but MS is known for this...)
