Fixed issues

  • We’ve fixed the issue causing ARM devices to receive a bugcheck and have removed the block with this build.
  • We fixed an issue that could result in the Optional Features page in Settings appearing blank.
  • We’ve fixed an issue where, when running corruption repair (DISM), the process stopped at 84.9%.
  • We fixed an issue where, after successfully completing installation of an update and rebooting the device, the Start menu Shutdown button still showed Update and Shutdown and Update and Restart.
  • We fixed an issue that could result in Windows updates failing with error 0x80070003.
  • We fixed an issue that could sometimes result in Settings crashing when pausing updates or the Windows Update settings page not loading.
  • We fixed an issue from the previous flight that was resulting in extra lines appearing in the taskbar jumplist.
  • We fixed in an issue resulting in a black window, with only a mouse being visible to others, when sharing a single app over Microsoft Teams.

Known issues

  • We are aware Narrator and NVDA users that seek the latest release of Microsoft Edge based on Chromium may experience some difficulty when navigating and reading certain web content. Narrator, NVDA and the Edge teams are aware of these issues. Users of legacy Microsoft Edge will not be affected. NVAccess has released a NVDA 2019.3 that resolves the known issue with Edge.
  • We’re looking into reports of the update process hanging for extended periods of time when attempting to install a new build.
  • Some devices may experience a bugcheck (GSOD) during the reboot to install this update. If this happens, log in, schedule a time for the update to install, and then log off all user profiles before the scheduled install time. The install will then proceed as expected.
  • The Documents section under Privacy has a broken icon (just a rectangle).
  • When trying to use Win + PrtScn to capture a screenshot, the image is not saved to the Screenshots directory. For now, you’ll need to use one of the other options for taking screenshots, such as WIN + Shift + S.
  • Sticky Notes windows can’t be moved. As a workaround, when you set focus to Sticky Notes, press Alt + Space. This will bring up a menu that contains a Move option. Select it, then use either the arrow keys or the mouse to move the window.
  • We’re looking into reports of some Insiders receiving driver compatibility warnings when attempting to update to a newer build in certain virtual environments.
