How to fix Xbox sign-in failure after installing Windows 10 build 14942

Microsoft is now rolling out Windows 10 build 14942 for PCs enrolled in the Fast ring of the Windows Insider program. The new release part of the Redstone 2 update brings some new features, changes, and improvements.

One of these new improvements include changes to how the operating system handles service hosts. While in the past grouping services into service hosts was used to save memory, now with computers featuring more than enough RAM, the memory-saving advantage has dramatically decreased.

On Windows 10 build 14942 and later, most service hosts are no longer grouped. Instead, they are split into separate processes on devices featuring 3.5GB+ of RAM. Unfortunately, as a result of the change, users may encounter issues trying to sign into games that use Xbox Live.

However, Microsoft is aware of the issue and is offering a workaround until there is a permanent fix.

In this Windows 10 guide, we'll walk you through the steps to successfully sign-in to games that use Xbox Live if you're running Windows 10 Redstone 2 (build 14942).

How to fix Xbox sign-in failure on Windows 10 build 14942

  1. Use the Windows key + X keyboard shortcut to open the Power User menu and select Command Prompt (admin).
  2. Type the following command and press Enter:REG ADD HKLM\SYSTEM\CurrentControlSet\Services\XblAuthManager /v SvcHostSplitDisable /t REG_DWORD /d 1 /f

  1. Reboot your computer to complete the task.

When you restart your system, the XblAuthManager will now share a service host process with Windows Update and Background Intelligent Transfer Service, which will allow you to sign back into Xbox Live.

You can learn more about the service hosts changes and everything included on Windows 10 build 14942 in our dive deep article.

  • Windows Central to the rescue, again!
  • I want that Wallpaper so bad :D Btw thanks for the Workaround :)
  • thanks heaps for that. I'm rocking it now :)
  • I try that and it says: acces refused. Posted via the Windows Central App for Android
  • Make sure you're a administrator and running cmd as admin too.
  • Yeah, I forgot to open as an admin. It works now. Posted via the Windows Central App for Android
  • Anyone able to send me an invite to join Xbox insider? GT: JoeGould
  • I should have my own invataion coming in the next few days - I shall send one your way - David T Rex
  • Thanks!
  • Thanks for the help guys. This one was driving me mad!
  • Thanks for making this an article, it needed to be as soon as this issue was reported. Oh, has anyone else been able to play Gears of War 4 on this build? I assumed it was related but I was able to use this workaround to fix the other apps/games. Only Gears of War 4 still crashes on launch .
  • i fixed the problem but all my uwp games crash on launch
  • This has been happening to me for the past five days.
  • Before the build was released?
  • Worked once, now unable to sign in again.
  • Hopefully Windows devs are reading these articles and implement the fixes for the next build/update Posted via the Windows Central App for Android
  • This fix is from Microsoft so they'll definitely be aware of it and look to fix it in future builds
  • Still can't play ReCore on these builds.  It wasn't crashing but, I couldn't log into XBox to restore saved games and now after doing this, it just crashes.
  • tried this and it fixed one problem and gives another where it just attempts to and ultimately refuses to sign in...just in time for gears
  • Thanks again Mauro, that fixed it for me!
  • I did this command and did it a second time but replaced the service name with XblGameSave, as that's the crashing error in the event logs for UWP games.  I was able to get Rise of the Tomb Raider and Forza 6 Apex running.  Still getting remote procedure call errors for Gears 4, but I'm trying other services to see if I can get it to work.  A little reckless, I know, but....I wanna play! :) I did this on the listed build here (14942) and 14946 with positive results.
