I Can't Sign Into the Windows 10 Xbox App

You can't change a gamertag into a previously owned one but you could sign in to the Windows 10 Xbox app with the old one though.

Hi Noah,

Thanks for the reply clarifying that you are using the Xbox (Beta) app and cannot sign in. If you've already confirmed that you're able to sign in at account.microsoft.com or at xbox.com and are still experiencing the issue, then here is what you can next
try to see if this will get the app in a working state to receive your credentials.

As you've already confirmed that you've updated your PC to the latest version of Windows 1903, then you may need to try performing a clean boot to get it in working order. This helps eliminate software conflicts that occur when you install a
program or an update or when you run a program in Windows 10. Here's a link on
how to perform a clean boot in Windows.

Give this a try and let us know the results.

I hope that this helps out.

Hi Noah,

Thanks for reaching out to us in the forums for this issue. Are you attempting to sign into the Xbox Console Companion app (formerly Xbox app) or the Xbox (Beta) app? To access Game Pass for PC, you would need to do so from the Xbox (Beta) app.

How do I get the Xbox (Beta) app?

Hello, justinparks6170. Thanks for reaching out! My name is Lucas, and I'm an Independent Advisor and a Microsoft user just like you. I'll be happy to assist you today.

If you uninstalled Microsoft Store, you will need to install it again to run and sign in to the Xbox app. Please follow the steps below:

- Go to Start > Type PowerShell > Right click it and select “Run as administrator” > Type the following command and press Enter:

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

- Restart your computer. Go to Start > Search for Store and see if the Microsoft Store appears. If it is there, click on it and sign in with your Microsoft account. Then, open the Xbox app and see if the error 0x87DD0005 still appears.

Let me know how it goes.

I did a clean boot and I still couldn't sign into the Xbox (Beta) app. It just refreshes the current page when I click sign in.
