Microsoft has released a fresh new insider build update for Windows Insiders in the Fast Ring.



Build 19631 is now rolling out and adds a few improvements to Windows Hello and Windows Sandbox.



With this build, Windows Hello should be working fine now as the configuration has been updated to accommodate 940nm wavelength cameras.



Similarly, WSB files are now case insensitive.



Microsoft has also released ARM64 VHDX as a download for Insiders with Windows 10 Insider Preview Build 19624.



This will enable users to run Windows 10 as a guest OS in Hyper-V.


You can download the VHDX here.

Note: Hyper-V on Windows 10 ARM64 devices only works on Windows 10 Insider Preview Builds 19559 and above. Nested virtualization is not supported.

General changes & improvements

• We updated the configuration of Windows Hello to make sure it works well with 940nm wavelength cameras.
• Windows Sandbox WSB files are now case insensitive.

Fixes

• We fixed the issue causing the IIS configuration being set to default after taking a new build.
• We fixed an issue that could result in a key press not waking up a device from connected standby in certain scenarios.
• We fixed an issue impacting Remote Desktop reliability.

Known issues

• We’re looking into an issue where some devices booting from eMMC storage may bugcheck when resuming from hibernate.
• We’re looking into reports of the update process hanging for extended periods of time when attempting to install a new build.
• We’re working on fixing an issue for a future Insider Preview build where in Settings > Privacy the Documents and Downloads sections show a broken icon next to their page name (just a rectangle).
• We’re looking into reports that taskbar preview thumbnails aren’t rendering consistently (showing a blank area).
