I have been in contact with HP's support, and their case managers are suppose to call me within the next few days. My impression in conversing with them they will be forwarding the information to MS. So far in the last few days my computer has gone into
sleep mode properly without the home groups. I guess we shall see.
The IPV6 I have tried on two occasions and that hasn't worked for me. The only solution after several numerous days and tries is to disconnect from the homegroup.
Difficult for me with so many having this problem, that it didn't show up on there trials.
