xbox master chief collection Error code: (0x8007042b)

Hello, Klick37. Thanks for reaching out. I'm Lucas, an Independent Advisor and a Microsoft user just like you. I'll be glad to help you out.

After that:
- Completely uninstall Halo MCC and Xbox App (and Xbox Companion App if you have it). Use their own uninstaller (just search for Xbox on Windows Start and click on uninstall).

- After uninstalling, go to Start > Type PowerShell > Right click it and select “Run As Administrator” > Type the following command and press Enter (you can run one at a time):
Get-AppxPackage Xbox | Remove-AppxPackage
Get-AppxPackage Microsoft.XboxApp | Remove-AppxPackage
Get-AppxPackage Microsoft.GamingServices | Remove-AppxPackage –allusers

(If you receive an error when executing any of these commands, don't bother. Just follow the other steps here)

- Press Windows + R and type in "regedit". Press enter.

- Search for HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services

- Delete "GamingServices" and "GamingServices.net" (if they're still there).

- Click on Start > Credential Manager > Windows Credentials. Search for Xbl|DeviceKey, click on it and then Remove.

- Delete Accounts and Cache folders at:
C:\Users\Username\AppData\Local\Packages\Microsoft.XboxIdentityProvider_8wekyb3d8bbwe\AC\TokenBroker

- Also delete Microsoft Store local cache files at:
C:\Users\Username\AppData\Local\Packages\Microsoft.WindowsStore_8wekyb3d8bbwe

- Go to Start > Settings > Apps > Apps & features > Microsoft Store > Advanced Options > Reset.

- Go to Start > Settings > Gaming > Xbox Networking > Fix it.

- Go to Start > Settings > Gaming > Game Mode > Set if OFF.

- Go to Start > Settings > Accounts > Sign-in Options > Privacy > Uncheck "Use my sign-in info to automatically finish setting up my device and reopen my apps after an update and restart."

- Press the Windows Key + R. Type WSReset.exe and press Enter.

- Restart Windows.

- If you're using a proxy, please stop using it for now:
- Press Windows Key + R. Type inetcpl.cpl and press Enter. Click the Connections tab, and then click LAN settings. Uncheck the Use a proxy server for your LAN check box. Click Ok.

- Please check if Date and Time is set correct. Uncheck "Set the time automatically", do it manually.

- Open Microsoft Store and make sure you are logged in with the correct account.

- Finally, install Xbox App (and Xbox Companion App if you had it) again. Open it and login to the correct Microsoft/Xbox account.

Download, install and try to play Halo MCC, see if it still gives you the error and please let me know.

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello Klick37, have you checked if you have the latest version of Windows installed, at 21H2, because recently came out the latest update to Windows 10 and 11.

See which version of Windows 10 you have

https://support.microsoft.com/en-us/windows/see...

Updates often seen as optional, Microsoft released major fixes this week, and make sure you have the Xbox Companion App installed.

If you haven't updated yet, click the link below, update and then make all subsequent security updates.

Download Windows 10

https://www.microsoft.com/en-us/software-downlo...

Download Windows 11

https://www.microsoft.com/en-us/software-downlo...

Also make sure all Xbox Apps are up to date in the store, and make sure you have the Xbox Companion App installed, it works with the Xbox App.

Since it still doesn't work, I'd suggest you to create another Windows local account:

Press Win+R Keys.
Type netplwiz and press Enter.
Click Add button.
Click Sign in without a Microsoft Account. If you do not see that option, disconnect from the Internet.
Click Local account if prompted.
Type the username you want, and the password. You must also specify a hint. Click Next.
Click Finish.

Make the new local account an admin account:
Select Start > Settings > Accounts > Family & Other Users > Select the Account Owner Name (you should see "Local account" below the name) > Change Account Type.
Select Administrator, and then select OK.
Sign in with the new Administrator Account.

After that:
Go to Start > Type Services > Open it.
Find all Xbox Services (Xbox Accessory Management Service, Live Auth Manager, Live Game Save, Live Networking Service). Right Click > Properties> Set the startup type to Automatic. Also Start them.
Go to Start > Settings > Accounts > Sign-in Options > Privacy > Uncheck "Use my sign-in info to automatically finish setting up my device and reopen my apps after an update and restart."

Restart your PC.

Also, remove any old device from your Microsoft Account:
Go to https://account.microsoft.com/devices, sign in, and find any old device.
Select Show details to see info for that device.
Under your device's name, select More actions > Remove.
Review your device details, select the check box, I'm ready to remove this device, then select Remove.

After that, go to: https://account.microsoft.com/devices/content and remove the old device from this too.
Find the device you want to remove and select Unlink.
Review your device details and select Unlink.

Let me know how it goes.

Nothing works and my patience is at an end. I have terminated the gamepass subscription. thanks anyway for your help.

bye

There have been quite a few threads recently about the same thing... and there are complaints on halowaypoint. It seems that the Season 8 Update broke something for PC players on the Microsoft Store/Game Pass versions.

Some users said that this was fixed by doing this:

Go to Start - Settings - Time and Language - Region

Make sure the country matches your Microsoft/Xbox Account and set the region format to English (World)

See if this helps and let me know.
