Not really sure about the specific solution, since I am not familiar with this problem, but on that MS site you can see applications which disable some things, and applications which enable the same things back (e.g. "Disable IPv6 on all nontunnel interfaces" and "Re-enable IPv6 on all nontunnel interfaces"). So this sounds like something safe to do. If you are using many computers, I would suggest isolating only one, and checking one by one if applying the fixes changes anything.
