I can't login and play my xbox games on pc

Dear tomkat7,

Thank you for reaching out to the Microsoft Q&A Forum.

Based on all the screenshots and your description, you are correct: this is not a problem with the individual games. This is a systemic problem with your Windows profile's ability to authenticate with Xbox Live and access cloud storage.

You could try following these steps below to solve this issue:

1. Repair and reset core apps:
   • Press the Windows + R, type wsreset.exe, and press Enter. A blank black window will appear. Wait for it to close and for the Microsoft Store to open.
   • Go to Settings > Apps > Apps & features.
   • Find Microsoft Store in the list, click the three dots (...) > Advanced options > Repair. After it finishes, click Reset.
   • Find Xbox in the list, click the three dots (...) > Advanced options > Repair. After it finishes, click Reset.
   • Find Game Services in the list, click the three dots (...) > Advanced options > Repair. After it finishes, click Reset.
   • Restart your PC and try launching the Xbox app.
2. Fix Xbox networking:
   • Go to Start, type cmd, right-click on Command Prompt > Run as administrator.
   • Run this command:

          netsh interface teredo set state type=default
     

   • Restart your computer.
   • After restarting, open the Xbox app. Go to Settings (click your profile picture) > Network. Wait for the test to run. It should say "NAT Type: Open" or "Moderate" and "Server connectivity: Connected". If it shows "Teredo is unable to qualify," this was the problem.
3. Test with a new local administrator account:
   • Go to Settings > Accounts > Other users.
   • Click Add account (next to "Add other user").
   • On the Microsoft login pop-up, click "I don't have this person's sign-in information."
   • On the next screen, click "Add a user without a Microsoft account."
   • Enter a username (e.g., testuser) and a password.
   • Once the account is created, go back to the Other users screen. Click on the new testuser account and click Change account type.
   • Change it from "Standard User" to "Administrator" and click OK.
   • Sign out of your main account (Start Menu > Your Profile > Sign out) and log in as the new testuser.
   • Once on the new desktop, open the Microsoft Store and Xbox app. Log in with your email account.
   • Try to install and launch one of the broken games.
   If the game works on the new testuser account: This confirms your original Windows user profile is corrupted beyond repair. The only solution is to migrate your personal files from your old profile to the new one and use the new profile from now on.

Hi tomkat7,

Thank you so much for this critical follow-up.

You are absolutely right about the UI changes:

• In Windows 11 24H2, "Apps & features" is now "Installed apps". Your steps were correct.
• Thank you for the update on the Xbox app; they must have removed the "Network" tab, which makes troubleshooting more difficult.

The most important piece of information you have provided is this:

• State: offline
• Error: client is in a managed network

This is the root cause of all your problems. You could try some steps below to solve this:

1. Uninstalled all VPN software:
   • Go to Settings > Apps > Installed apps.
   • Look for any VPN software (NordVPN, ExpressVPN, Surfshark, ProtonVPN, etc.).
   • Click the three dots (...) and Uninstall every single one.
   • Restart your computer.
   • After restarting, open Command Prompt (Admin) and run this command again: netsh interface teredo show state. See if the State is now qualified or dormant instead of offline. If it is, launch the Xbox app.
2. Fix the Teredo adapter in Device Manager:
   • Right-click the Start button and select Device Manager.
   • At the top, click View > Show hidden devices.
   • Expand the Network adapters section.
   • Look for any adapters with "Teredo" in the name (e.g., "Teredo Tunneling Adapter").
   • If it has a yellow exclamation mark, right-click it and select Update driver.
   • If that doesn't work, right-click it and select Uninstall device.
   • Restart your computer. Windows will automatically reinstall it.
3. Fix Teredo via the Registry:
   • Click Start, type regedit, and press Enter to open the Registry Editor.
   • Copy and paste this path into the address bar at the top and press Enter: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters
   • In the right-hand pane, look for a value named DisabledComponents.
   • If this value exists, right-click it and delete it. (Or, if you are cautious, double-click it and set its value to 0).
   • Restart your computer and test the netsh interface teredo show state command again.
   Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

If all solutions above do not work, the only remaining solution is to Reinstall Windows with the installation media - Microsoft Support 

Disclaimer: At this point, we have exhausted all troubleshooting and I recommend that we try to perform a clean install to get your computer back into a working condition. Please ensure that you backup any important data, including Documents, Pictures, Videos and more. 

Please let me know if these solutions could help.

Ignore all previous answers - the ultimate fix is running this: https://support.xbox.com/en-US/help/games-apps/troubleshooting/gaming-services-repair-tool on a Windows PC as an admin. May require admin privileges for the user impacted - I did not test without them. If so, just temporarily make them an admin then revoke it.
