Microsoft releases Windows 10 Insider Preview Build 19628 to the fast ring

Microsoft have released a new Windows 10 build for Windows Insiders on the fast ring. Build 19628 is from the MN_RELEASE branch rather than the RS_PRERELEASE branch that builds normally come from. Microsoft say this is because they are testing changing rings:

 In this case, we are practicing our ability to change which branch we consider as the active development branch. This is just a short-term change and we intend to release builds from RS_PRERELEASE again soon. As our engineers work in development cycles internally, we may prioritize work being done in a specific branch and may need to move Insiders between branches.

The main change with this build is support for DNS over HTTPS. This is the first build of Windows 10 that supports this security feature. You can read more about it on Microsoft’s blog.

General changes & improvements

We’re adding initial support for DNS over HTTPS, so that you can opt into using encryption when Windows makes DNS queries. Follow the instructions in this blog post to opt in as it will be off by default.

Known issues

We’re aware Narrator and NVDA users that seek the latest release of Microsoft Edge based on Chromium may experience some difficulty when navigating and reading certain web content. Narrator, NVDA and the Edge teams are aware of these issues. Users of legacy Microsoft Edge will not be affected. NVAccess has released a NVDA 2019.3 that resolves the known issue with Edge.

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 of IIS configuration being set to default after taking a new build. You will need to back up your IIS configuration and restore it after the new build is installed successfully.

We’re looking into reports that taskbar preview thumbnails aren’t rendering consistently (showing a blank area).
