Error 0x80073cf9 is a generic Windows app installation/update failure. For the Xbox app on Windows 11, focus on fixing Microsoft Store and Gaming Services, because the Xbox app is delivered and updated through them.
Try these steps in order (skip anything already done):
- Update Windows
Go to Start > Settings > Windows Update > Check for updates and install all available updates. This ensures Store and app components are current. - Reset Microsoft Store’s cache
- Close Microsoft Store and the Xbox app.
- Press Windows + R, type
wsreset.exe, and press Enter. - A blank window appears and then Microsoft Store will reopen automatically.
- In Store, confirm you are signed in with the same account intended for the Xbox app.
- Repair/Reset Microsoft Store and Xbox app
- Open Settings > Apps > Installed apps.
- Select Microsoft Store > Advanced options and choose Repair, then test. If still failing, choose Reset.
- Do the same for the Xbox app.
- Ensure Gaming Services is healthy and up to date
Gaming Services is required for Xbox app sign‑in and game management. To force a clean reinstall:- Open PowerShell as Administrator.
- Run:
get-appxpackage Microsoft.GamingServices | remove-AppxPackage -allusers - In the same PowerShell window, run:
start ms-windows-store://pdp/?productid=9MWPM2CQNLHN - In the Store page that opens, install Gaming Services, accepting any UAC prompt.
- When installation completes, try opening the Xbox app again.
- Reinstall the Xbox app via Store
If the error persists:- Uninstall the Xbox app from Settings > Apps > Installed apps.
- Open Microsoft Store, go to Library, find Xbox, and select Install.
- Launch the Xbox app and sign in.
If downloads or updates in Microsoft Store itself are stuck or not starting, also:
- Verify the Microsoft Store Install Service is running (via
services.msc→ set to Automatic and Start if needed). - Use the built‑in Windows Store Apps troubleshooter from Settings > System > Troubleshoot (Windows 11) to detect and fix Store issues.
These steps address the underlying Store/Gaming Services problems that typically cause 0x80073cf9 when updating or opening the Xbox app.
