New features and changes[edit | edit source]

  • HTTP/2 performance was improved thanks to Cubic, which is the new default TCP congestion provider.
  • Improved the security of Microsoft Edge by using HTTP/2 preferred cipher suites.
  • When the user is asked to restart for new builds, they are first asked to restart for the first couple of days, after that, the user is asked to automatically schedule restarts outside of their active hours.

Bugs[edit | edit source]

  • Clicking a link to launch an app from another app sometimes may not work.
  • 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.
  • If you delete a locally-stored folder that is synced to OneDrive, the system will crash with a green screen of death.
