You paid dearly for your OS. Call it in.
HOWEVER I never see your issue but then again I never accept a driver update from Microsoft. Many do and this happens.
There is also some malware that causes ethernet, wifi or USB to fail on updates or even when you remove the malware with antivirus or other tools. It's sad that folk will blame the updates or antivirus instead of the malware.
whenever there is windows 7 ultimate update my wireless USB will get knock off line.
