  • The EdgeHTML engine used by the Microsoft Edge browser has been updated from version 15 to 16.

Bugs and quirks[edit | edit source]

  • By default, this build is not bootable on some devices such as Lumia 930. As such, it is required to replace winload.efi with a copy from build 16235 for this build to be able to boot on these devices.
  • The Splash composer is completely broken in this build, requiring the use of the CShell composer instead.
  • The built-in screenshot feature cannot save screenshots at the correct resolution.
  • The progress bar in Windows Update is not displayed.
  • Several blank tabs are occasionally displayed in the tab page of Microsoft Edge.
