Windows 10 build 20246 is the nineteenth Insider Preview of Iron. It was released on 29 October 2020 to all Windows Insiders on the Dev Channel. It is also the first released build from the  branch.

Changes

 * Features such as redesigned touch keyboard, emoji picker, voice typing, and theme-aware splash screens introduced in previous builds have been removed temporarily.
 * Automatic Linux distro installation to the  command has been added.

Bugs

 * Live preview doesn't work for pinned site tabs on some machines.
 * There's a chance of randomly encountering a  BSOD.
 * In some PCs, the taskbar is obscuring the Power button in the Start menu blocking the access to its options. To workaround this issue, use the options from the User menu (Win+X).
 * ARM PCs will notice that Windows PowerShell will fail to launch on this build. To workaround this issue, use PowerShell (x86) and PowerShell ISE (x86).
