Microsoft releases new Windows 10 preview with 9 bug fixes ahead of April 2019 Update

Microsoft today released a new Windows 10 preview with nine bug fixes. The update bumps Windows 10 from build 18348 (made available to testers on March 1) to build 18351. These builds are from the 19H1 branch, which represents the Windows 10 update that will arrive in the first half of this year (likely finalized for Windows Insiders this month and rolled out to the public in April).

Windows 10 is being developed as a service, meaning it receives new features on a regular basis. Microsoft has released six major updates so far: November Update, Anniversary Update, Creators Update, Fall Creators Update, April 2018 Update, and October 2018 Update.

We don’t yet know if the next update will be called the Windows 10 April 2019 Update. We do know, however, that it will bring Windows 10 to version 1903.

Bug fixes and known issues

This 19H1 build includes the following general bug fixes and improvements:

  • Fixes to improve the download and install experience of State of Decay.
  • Fixed an issue from recent builds that could result in monitors being missing from the built-in Color Management application.
  • Fixed an issue causing Explorer.exe to crash for some Insiders when Jump list content was updated.
  • 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.
  • Fixed an issue where the time shown on the clock in Windows Sandbox might not match the clock outside of Windows Sandbox.
  • Fixed an issue resulting in Emoji 12 emoji showing up as boxes in certain XAML text fields.
  • Fixed an issue where text scaling values did not persist across upgrades for Win32 applications.

This build has eight known issues:

  • Launching games that use anti-cheat software may trigger a bugcheck (GSOD).
  • Creative X-Fi sound cards are not functioning properly.
  • More night light issues.
  • Some Realtek SD card readers are not functioning properly.
  • The Chinese versions of multiple games are not working.
  • Region settings are being reset on upgrade for some Insiders.
  • VMware cannot be installed or updated on Windows Insider Preview builds. Hyper-V is a viable alternative.
  • 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.

As always, don’t install this on your production machine.
