If you are encountering Xbox errors 0x903f900a or 0x803f900a on your Windows 11 device, it can be frustrating. These errors usually appear when trying to launch Xbox games or apps and are related to licensing or account issues.

Fortunately, there are several easy and effective ways to fix these problems. This guide will walk you through each step in a simple and detailed manner.

By following the instructions below, you can get your Xbox games running smoothly again on Windows 11.

Let’s start with some quick checks before diving into the troubleshooting steps.

Quick Note: Prerequisites and Initial Checks

  • Check your internet connection: A stable internet connection is essential for verifying game licenses and account details.
  • Sign in with the correct Microsoft account: Make sure you are logged into the same Microsoft account that owns the game or app.
  • Ensure Windows 11 is updated: Running the latest updates can fix bugs related to Xbox services.
  • Verify the Xbox app is updated: Open Microsoft Store and check for any updates for the Xbox app or Xbox Game Pass app.

Step 1: Restart Your PC and Xbox App

Before trying anything complicated, simply restart your computer. This can clear temporary glitches and refresh connections.

After rebooting, open the Xbox app again and try launching the game. Often, this simple step resolves many issues.

Step 2: Check Your Xbox Live Service Status

If Xbox Live services are down or experiencing issues, you might see these errors. To check:

  • Go to the official Xbox Live Status page.
  • Look for any alerts or outages related to Xbox services like Store, Authentication, or Game licenses.

If there are issues, wait until Microsoft resolves them before trying again.

Step 3: Sign Out and Sign Back Into the Xbox App

Sometimes, your account session may have expired or become corrupted. To fix this:

  1. Open the Xbox app.
  2. Click on your profile icon in the top-right corner.
  3. Select Sign out.
  4. Close the app completely.
  5. Reopen the Xbox app and sign back in with your Microsoft account.

This refreshes your account connection and can fix license verification errors.

Step 4: Reset the Microsoft Store Cache

The Microsoft Store manages downloads and licenses for Xbox games. Sometimes, its cache can cause errors.

To reset the cache:

  1. Press Windows + R keys to open the Run dialog.
  2. Type wsreset.exe and press Enter.
  3. A blank Command Prompt window will open, and after about 30 seconds, it will close automatically.
  4. The Microsoft Store will open, indicating the cache has been cleared.

Try launching your game again after this step.

Step 5: Run the Windows Store Apps Troubleshooter

Windows 11 has a built-in troubleshooter that can detect and fix problems related to Microsoft Store apps, including Xbox games.

  1. Click on the Start menu and select Settings.
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Windows Store Apps in the list.
  4. Click Run beside it.
  5. Follow the on-screen instructions to complete the process.

This can automatically fix licensing or app-related issues causing errors 0x903f900a and 0x803f900a.

Step 6: Reinstall the Problematic Game or App

If none of the previous steps worked, try reinstalling the game or app:

  1. Open the Xbox app or Microsoft Store.
  2. Go to your game library and locate the affected game.
  3. Click on the game and select Uninstall.
  4. After uninstallation completes, reinstall the game.

Reinstalling ensures you have the latest files and resolves corrupted installations.

Step 7: Check Date and Time Settings

Incorrect date and time settings can cause authentication and license verification failures.

To check and fix this:

  1. Right-click the clock on the taskbar and select Adjust date and time.
  2. Make sure Set time automatically and Set time zone automatically are turned on.
  3. If they are on, you can try toggling them off and back on again.

Step 8: Advanced Option – Re-register Xbox and Store Apps Using PowerShell

If you are comfortable using PowerShell, re-registering the apps can fix deeper software issues.

  1. Press Windows + X and select Windows Terminal (Admin) or PowerShell (Admin).
  2. Copy and paste the following command and press Enter:
Get-AppxPackage -allusers *WindowsStore* | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}
  1. Wait until the command finishes processing.
  2. Then, run this command to re-register Xbox app:
Get-AppxPackage -allusers *xboxapp* | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}

Restart your PC after running these commands.
