Xbox Live Multiplayer on PC

I think that this link might be of some help: How to use multiplayer in Xbox Live games on Windows 10 PCs

Please let us know if this helps with your issue.

The Xbox One disc will not work on your PC. Even if you install Windows 10 via Bootcamp, the Xbox disc won't be recognized. Not even on "real" Windows 10 PCs.

So to answer your questions:

1.) You would need to buy an actual PC version of Call of Duty.

As for Multiplayer: Only the crossplay enabled multiplayer modes will work. You can't play campaign, ranked multiplayer or tournaments.

2.) On the PC you do NOT need a Xbox Live subscription. But the person playing on the Xbox One S would STILL need Xbox Live (or have an Xbox Live owning Account set that console as their Home Console).

It might be free to play on other consoles and PC but Xbox requires you to have Xbox Live to play multiplayer games.

I had the same problem with the Teredo issue and could not use the parties at all until for a long time. This is how I fixed it:

Click on the search bar and type in cmd. Right click on Command Prompt and click Run as administrator





Run the following command from the Admin command prompt:

netsh advfirewall show currentprofile





If the following Firewall policy is present, you don't have to change anything:

Firewall Policy : BlockInbound, AllowOutbound



If it says AllowInbound instead, this is where the party issue originated.

To set the firewall policy to the correct one, run the following command from the Admin command prompt:

netsh advfirewall set currentprofile firewallpolicy blockinbound,allowoutbound





Hopefully the party will work now. If it doesn't, don't worry, there's one more fix we can try:

Run the following command from the Admin command prompt:

reg query HKLM\System\CurrentControlSet\Services\TcpIp6\Parameters





If the output includes the following line, and the value displayed is not 0x0, Teredo may have been disabled:



DisabledComponents REG_DWORD 0x8e

To re-enable Teredo, type the following line:

reg add HKLM\System\CurrentControlSet\Services\Tcpip6\Parameters /v DisabledComponents /t REG_DWORD /d 0x0





At this point, everything should be fixed. I hope this helps and if you encounter any issues, please post again and include pictures of any issues you encountered if possible

Don't worry, this can be fixed! Before trying the fix as it's quite complicated , try this first: make sure you're using the
Xbox App on PC for the voice chat and not the console companion app as the Xbox app is much more reliable in terms of parties. Once in the app, click on Social then
Chat, then create a new chat and add all of your friends. Then your friends can join the voice channel without an invite similar to Discord. Keep in mind that
your friends can't open the voice channel on Xbox, it has to be done on PC. Once you created the chat, just
click on the headset icon while in the chat to open the voice channel.
Your friends can then go to Parties and Chats on their Xbox guide, go into chats, click on the chat and click join voice.





I'll post the fix in the next reply as it's quite long
