How to fix sign-in error code 0x800488AB in the Xbox app for Windows 10

If you've been cursed by a sign-in error with the code 0x800488AB in the Xbox app for Windows 10, fear not, there is an easy fix.

The error window will tell you to go to and sign in to fix an issue with your account. But you don't need to do that. It doesn't fix anything, anyway.

Here's what you need to do.

1. Click on sign in with a different Microsoft account

You'll find the option you need under "Use another account" as highlighted in the image above. While this image doesn't show the actual error, you will still find the option in the same place, the window will just look a little different.

2. Don't click on your own Microsoft Account

Your Xbox Live Microsoft Account that is usually connected to the Xbox app will be offered as an option. Don't click on it.

3. Click on the option for a new Microsoft Account

Use the option highlighted in the image above. Then, simply enter your Microsoft Account details again, click login and you should find yourself back into the app, error free.

It might not work for all of the people, all of the time, but we've encountered it first hand and these steps helped us back into the app.

  • WC has to be the top site for Windows PC, mobile, Xbox, and Windows10 in general, news and help around the world....
    If it's not yet,, they are definitely trying to be, and are taking full advantage of the W10 launch... Looks as though they've been planning this for months, and I bet with the help of MS.
    Sooner, or later, I would think that WC will be Mobile Nations bread, and butter, with more traffic than iMore, and Android Central, combined... That's gotta lend credibility to the ecosystem...
  • We're a way off Android Central level traffic (right now :P), but thanks for the kind words! Without the guys who come here every day we wouldn't be able to do any of it :)
  • Well good luck, I hope you get there! I've made reading your articles part of my day to day schedule!
  • If you guys keep up this level of commitment one day you'll be sitting on the shelf next to PC world.. Lol
  • Lol, I doubt they want to be sitting on a shelf somewhere :P.
  • Windows 10 _ Released to early full of Snags Just got over continual reboot problem _ NOW THIS!!!!!!
  • Well, this is more of an Xbox Live sign-in issue. And Xbox Live and regular problems (sadly) seem to go hand-in-hand
  • Issues like this aside, the new way Windows 10 is handling accounts for its native apps is fantastic. It really embodies Satya's vision of allowing you to combine work and personal on one device. For instance I use a work Microsoft account for all my work devices, and in Windows 8 that meant I couldn't access my personal music subscription from my work computer. Now I can just add my personal account and set Groove to use that instead of the main account I'm logged in as. I can also add my work account to my personal phone and access work files via OneDrive. It's fantastic.
  • Not even home to see if I have this issue but I now know how to fix it. Awesome!
  • I just waited a couple of hours and then it was good
  • I wished they would fix the issue where if you open the app. All you get is a green screen in the app. Sometimes I have to close and open the app like 5 times.
