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.
