Today, Microsoft is releasing Windows 10 Insider Preview build 19631 to the Fast ring. As usual, there aren’t any new features, and just like last week, it comes from the mn_release branch. However, as we reported last week, this is still not 20H2, despite the branch that it comes from. 20H2 is going to be an enablement package, just like we saw with 19H2.
The Fast ring should be reserved for the prerelease branch, which means that the features you see aren’t tied to a specific release. Sure, it’s likely that most of the new features we’ve seen will arrive in 20H1, but that’s not confirmed.
The one new feature confirmed is that you can now get an ARM64 VHDX for Windows 10 build 19624, which can be used in Hyper-V on ARM64 PCs. While there aren’t any new features in this build, there are, as always, a bunch of improvements, fixes, and known issues. There’s one item under general changes and improvements:
- We updated the configuration of Windows Hello to make sure it works well with 940nm wavelength cameras.
Here’s what got fixed:
- 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.
- Windows Sandbox WSB files are now case insensitive.
- We fixed an issue impacting Remote Desktop reliability.
Finally, here are the 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).
As always, you can grab today’s build via Windows Update. If you’re not on the Fast ring yet, you can sign up through the Windows Insider Program tab in Settings.
