Changes[edit | edit source]

  • Officially enabled the Your Phone app. This app allows Android users to sync their photos to their computer, and for iPhone users, it allows them to send their browsing sessions to pick up where they left off from their phone to the computer.

Narrator improvements[edit | edit source]

  • This build includes reliability improvements to Narrator, including:
  • Improvements to Scan Mode regarding reading, navigating and selecting text.
  • Improvements to the link in the Narrator settings to relaunch QuickStart.
  • The aforementioned tutorial also now takes focus reliably.
  • Changed the keystroke to provide feedback to pressing Alt+F while in Narrator.
  • When Narrator's view is changed to read characters, words, lines or paragraphs, the Read Current Item command now reads the selected item more reliably.
  • The keystroke to move to the beginning of text has been changed to Narrator + B, while the keystroke to move to the end of text was changed to Narrator + E.
  • Improved usage of Braille commanding when using the Narrator key from the braille display.

Bugs[edit | edit source]

  • There are bugs impacting WDAG, Remote Desktop and Hyper-V. Users of the Remote Desktop Client (mstsc.exe) will see an incorrect error message saying the system is running low on virtual memory when a connection is being established. Users will have to leave the message there, or the connection will be severed if clicked on. In Virtual Machine Connection (vmconnect.exe), users won't be able to use an enhanced session.
  • The acrylic background on the taskbar flyouts (network, volume, etc) is missing.
  • When the "Make text bigger" option in the Ease of Access Settings page is used, text clipping issues may be encountered, and sometimes the text may not resize everywhere.
  • When Microsoft Edge is set up as the kiosk app, and you configured the start or new tab page from Settings, the browser may not be launched with the correct URL.
  • Sometimes the notification count icon can overlap with the extension icon on the Microsoft Edge toolbar when an extension has unread notifications.
  • If you're using Windows 10 in S Mode, when launching Office from the Microsoft Store, it may fail with an error message saying that a .dll file “is either not designed to run on Windows or it contains an error. Try installing the program again.” Sometimes uninstalling and reinstalling Office from the Store can fix the problem.
  • When using Narrator's scan mode, it may stop multiple times on a single control (an example is if there's an image present that doubles as a link).
  • When using Narrator's scan mode, ⇧ Shift with selection commands in Microsoft Edge, the text does not get selected correctly.
  • There's a chance of the Start menu causing performance and reliability issues in this build.
  • After you set up a Windows Mixed Reality headset for the first time on this build with motion controllers, the controllers may have to be re-paired a second time before appearing in the headset.
  • When using a Mixed Reality immersive app, saying "Flashlight on" may fail to turn on the flashlight feature even though the status appears as active on the Start menu.
