I refuse to arrange a support call with Microsoft and waste three hours only to be informed that they will need to reformat my machine, leaving me to re-install everything again. I guess my only option is to continue waiting patiently for someone at Microsoft to figure out how they managed to screw things up so royally.
Yes! Don't waste time on the phone. I got frustrated and tried calling these guys. They clearly have no idea what is causing this problem and will literally waste hours of your time with banal tasks, uninstalling all kinds of stuff, turning off silly registry keys - totally shooting in the dark. Eventually after your system is all hacked up you will be told to do a fresh install.
This is a known problem without a known solution - M$ needs to spend some time and fix the darn patch already.
