Evil MS Update KB2670838

When patching desktops in particular, this update in some instances kills all Aeroglass ability and Windows Desktop Experience management.  I first noticed this on my personal Windows 7 64 bit laptop with a 2GB Nividia card, the Aeroglass wouldn’t work and all my applications were running on strictly hardware only for video settings.
Some MS blogs point out this update is necessary for IE10, which already has a slew of problems for business environments.  My advice is to avoid this update until IE10 is ready for prime time!
