Actually,they found an issue but I think it has nothing to do with our problem here; http://support.microsoft.com/kb/2887595
"After you install this update on a computer that has certain drivers installed (including Rtbth.sys and Netr28x.sys), the computer may crash. Additionally, you receive an AV_NULL_IP_BTHUSB!USBD_CreateHandle error message.
We are working with the driver manufacturer to resolve this issue. For now, Windows Update does not offer this update for computers that have certain drivers installed (including Rtbth.sys and Netr28x.sys)."
