MIcrosoft Store keeps failing when trying to install a new app on my new PC

It sounds like you're experiencing a frustrating issue with the Microsoft Store on your new Windows 11 PC. Here are some troubleshooting steps you can take to resolve the error code 0xc0ea000A when trying to install apps:

1. Verify Microsoft Store Registration: Ensure that Microsoft Store is registered for your user account. You can check this by running the following PowerShell command in a non-elevated prompt:

      Get-AppxPackage *Microsoft.WindowsStore*
   

   If it indicates that Microsoft Store isn't installed, you may need to re-register it using an elevated PowerShell prompt:

      Add-AppxPackage -RegisterByFamilyName -MainPackage Microsoft.WindowsStore_8wekyb3d8bbwe
   

2. Check for Policy Restrictions: Sometimes, administrators can block access to Microsoft Store. Ensure that there are no group policies or configurations preventing you from using the Store. You can check for policies like RemoveWindowsStore that might be affecting access.
3. Firewall and Proxy Settings: Make sure that your firewall or proxy settings are not blocking the required endpoints for Microsoft Store. You may need to check if Windows Update endpoints are accessible, as they are necessary for installing and updating apps.
4. Use Windows Package Manager (winget): As an alternative to the Microsoft Store, you can use the winget command to install applications. For example:

      winget install Microsoft.Mahjong
   

   This can sometimes bypass issues with the Store itself.
5. Reset App Package: If the app still fails to start, consider using the Reset-AppxPackage cmdlet to restore the app to its original configuration. This can help if the app package is corrupted.

If these steps do not resolve the issue, you may want to check the event logs for more detailed error messages or consider reaching out to Microsoft Support for further assistance.

Hi Sallie DeMaio,

Thank you for reaching out to Microsoft Q&A forum. I understand how inconvenient it is to encounter the error 0xC0EA000A while trying to download Microsoft Store apps on a new Windows 11 PC. You’ve already tried several fixes, and I appreciate the effort you’ve put in.

Here’s what I recommend next to get this resolved:

Step 1: Repair Windows system files

Corrupted system components can cause licensing errors.

• Open Command Prompt as Administrator.
• Run these commands one after the other:

    DISM /Online /Cleanup-Image /RestoreHealth
    sfc /scannow
  

• Restart your PC and test the Microsoft Store again.

Step 2: Perform a Clean Boot

This helps rule out conflicts from third-party apps or services.

• Press Win + R, type "msconfig", and press Enter.
• In the Services tab, check the box that says Hide all Microsoft services, then click Disable all.
• Next, go to the Startup tab, click Open Task Manager, and disable all items that are not from Microsoft.
• Click OK and restart your PC then try installing the app. (You can re-enable everything later.)

*Disclaimer: A "clean boot" starts Windows with a minimal set of drivers and startup programs. It helps to determine whether a background service is interfering with your game or program and to isolate the cause of a problem.  These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by-step so that it will help you get back on track. 

Step 3: Create a new user profile

If the issue is tied to your current profile, a fresh one can confirm that.

• Go to Settings > Accounts > Other users.
• Click Add account > choose I don't have this person's sign-in information >Add a user without a Microsoft account.
• Enter a username and password > click Next.
• Sign in with the new user account, open the Microsoft Store to log in with your Microsoft account and try installing the app.

Step 4: In-place repair upgrade

If none of the above works, the most reliable fix is a repair install of Windows 11.

• Download the Windows 11 Installation Media from Microsoft.
• Run Setup.exe from within Windows.
• Choose Keep personal files and apps when prompted. This refreshes system components without deleting your data.

*Disclaimer: Let’s try performing an in-place install or in-place upgrade which will refresh your Windows files and operating system without removing files or applications. That being said, we always recommend that if you have important data, you should back it up before making large system changes. If you want to back up your data first, please do so. Once you are done backing up, you can follow the steps in the following guides:  How to run In-place upgrade in Windows 11 - Microsoft Q&A
