  • Taskbar flyouts (network, volume, etc) no longer have an acrylic background after upgrading to this build.
  • When you set up Microsoft Edge as your kiosk app and configure the start/new tab page URL from assigned access Settings, Microsoft Edge may not get launched with the configured URL. The fix for this issue should be included in the next flight.
  • Launching Office in the Store on Windows 10 in S Mode may fail to launch with error about a .dll not being designed to run on Windows. This should be fixed in upcoming flights.
