Heads up Windows Insiders, Microsoft has just released the 19H1 build 18351 for those of you on the Fast Ring. Microsoft is now done adding new features to the next major Windows 10 update, so this is another minor update with only bug fixes.

The release notes mentioned that the “Change how capitalized text is read” feature in Narrator has been disabled in this build due to reliability issue, and it’s worth noting that Microsoft still hasn’t fixed the issues related to anti-cheat software and Creative X-Fi sound cards. You can check the full list of bug fixes and known issues below:

General changes, improvements, and fixes for PC

  • If you haven’t been able to get the game State of Decay for free (for a limited time), we’ve just made more slots available! Whether you’ve tried it in earlier builds or haven’t had the chance yet, these instructions have everything you need. We’ve also made fixes to improve the download and install experience thanks to your feedback, so please try again if you had problems before.
  • We fixed an issue from recent builds that could result in monitors being missing from the built-in Color Management application.
  • We fixed an issue causing Explorer.exe to crash for some Insiders when Jump list content was updated.
  • We fixed an issue resulting in some devices unexpectedly experiencing a 30 second wait before pin re-entry was available after a pin was incorrectly entered on the lock screen.
  • We fixed an issue where the time shown on the clock in Windows Sandbox might not match the clock outside of Windows Sandbox.
  • We fixed an issue resulting in Emoji 12 emoji showing up as boxes in certain XAML text fields.
  • We fixed an issue where text scaling values did not persist across upgrades for Win32 applications.
  • Due to a Narrator reading reliability issue for the “Change how capitalized text is read” feature, the feature has been disabled starting in build 18351.
  • We fixed an issue where the mouse pointer color might be incorrectly switched to white after signing out and signing back in.

Known issues

  • Launching games that use anti-cheat software may trigger a bugcheck (GSOD).
  • Creative X-Fi sound cards are not functioning properly. We are partnering with Creative to resolve this issue.
  • While this flight contains some night light improvements, we’re continuing to investigate reported issues in this space.
  • Some Realtek SD card readers are not functioning properly. We are investigating the issue.
  • We’re investigating reports of the Chinese version of multiple games not working.
  • We’re investigating an issue where region settings are being reset on upgrade for some Insiders.
  • We’re investigating an issue preventing VMware from being able to install or update Windows Insider Preview builds. Hyper-V is a viable alternative if available to you.

Known issues for Developers

  • If you install any of the recent builds from the Fast ring and switch to the Slow ring, optional content such as enabling developer mode will fail. You will have to remain in the Fast ring to add/install/enable optional content. This is because optional content will only install on builds approved for specific rings.

If you want to do a clean install of the 19H1 update, be aware that Microsoft has also just released ISOs for the 19H1 build 18343 that shipped last week to Slow Ring Insiders. The ISO files are available to download on this page.

Microsoft is expected to complete the Windows 10 19H1 update (soon to be renamed “1903”) later this month, and you can expect a couple more builds to soon hit the Slow Ring and then the Release Preview ring. A full list of new features coming in the 19H1 update is available on this page.
