In order to participate in an Xbox party (Windows 10), I found that I had “Network” issues. After following the instructions located here; I was still left in a state that wasn’t working. In my case, the network “adapter” wasn’t even in the list… and even if I were to ignore the troubleshooting tips stating to not manually install the adapter; I couldn’t do that either as the adapter wasn’t in the list to be installed.
I did find this thread with the following suggestion:
netsh interface ipv6 set teredo client
After doing this and rebooting, the “adapter” was now in the list as expected and the “Network” tab in the Xbox app is connecting as desired.
