Windows 10 build 20206 is the eleventh Insider Preview build of Iron, the 21H1 development semester of Windows as a service. This build was released to Windows Insiders in the Dev Channel on 2 September 2020.

Changes[edit | edit source]

These changes are only available to a small group of Insiders at first, meaning that not everyone will see them right out of the box. They are available on both upgrades and clean installations since Cobalt build 21313.

Updated the emoji picker to be integrated with Fluent Design, added a search box, animated .GIF support and support for emojis to the clipboard history. Also added another area to Feedback Hub regarding .GIFs and other input.
Added voice typing. It is currently available for English, French, Brazilian Portuguese, Simplified Chinese, Spanish, German, Italian and Japanese languages.
Various improvements to the touch keyboard, notably including an emoji search.
Added the ability to change the text cursor's position with the space bar on the touch keyboard.

Enabling the new features[edit | edit source]

The redesigned emoji picker and the touch keyboard improvements are disabled by default in clean installations. To turn them on, use Vibranium Velocity/ViVeTool and use the command vivetool.exe addconfig 20438551 2 from an elevated Command Prompt window.

Bugs[edit | edit source]

The update process to this build has a chance of hanging for extended periods of time.
Live preview doesn't work for pinned site tabs.
Some Office applications may either crash or go missing if you update to this build.
There's a chance of the Settings app crashing if you open Manage Disks and Volumes.
The Linux kernel is not installed when you use the wsl --install in the Windows Subsystem for Linux. To workaround this issue, run wsl --update to the latest kernel version.
Sometimes, when starting up a WSL2 distro, there's a chance of randomly encountering the error “The remote procedure call failed”.
