Microsoft has just announced the release of the Windows 10 Insider build 20170 in the Dev Channel, which is a minor update compared to the previous build 20161 released on July 1. After introducing a revamped Start Menu in the previous flight as well as a consolidated Settings app, today’s build brings a new Sound Settings experience, a revamped Settings icon, as well as an experimental implementation of Transport Layer Security (TLS) 1.3.

It’s worth noting that Windows Insiders using devices with AMD processors won’t be able to install this build due to a bug causing stability issues on AMD-based devices. The Windows Insider team said that things should go back to normal with the next flight, but for all of you with Intel-based PCs, here’s what’s new, fixed and still broken in this new build:

What’s new in Build 20170

Improving your Sound Settings experience

Last week we mentioned we were planning on bringing more Control Panel capabilities forward into Settings, and here’s another one – we’re updating Settings > System > Sound > Manage sound devices to now let you know which device is default, and if not, enable you to set it as your default device or default communication device.

We’ve also updated the volume mixer to include a link to the per app audio settings, which you can use to redirect audio endpoints per app.

There is more work on the way in this area – stay tuned!

Changes and Improvements

As part of our ongoing efforts to update the iconography across Windows, Insiders will notice we’re introducing a new Settings icon in this build. The new Settings icon looks great on the Start menu with the theme-aware tiles introduced in Build 20161!

While we work on improving reliability, we’re temporarily turning off Notepad’s ability to persist open windows across restarts and updates.

An experimental implementation of Transport Layer Security (TLS) 1.3 is enabled by default starting with Insider Preview Build 20170. IIS/HTTP.SYS have TLS 1.3 enabled by default. SSPI callers can use TLS 1.3 by passing the new crypto-agile SCH_CREDENTIALS structure when calling AcquireCredentialsHanlde. SSPI callers using TLS 1.3 need to make sure their code correctly handles SEC_I_RENEGOTIATE.


  • We fixed an issue resulting in flickering when resizing certain apps when snapped side by side in tablet mode.

  • We fixed a race condition that could result in update notifications not appearing or appearing multiple times in quick succession.
  • We fixed an issue resulting in typing not working on certain keyboards in the previous flight – appreciate your patience while we investigated.
  • We fixed an issue that could result in modifier keys like Shift and CTRL sometimes being dropped over a remote desktop connection.
  • We fixed an issue resulting in a small number of Insiders experiencing an issue where Start wouldn’t launch in the previous build.
  • We fixed an issue that was increasing the amount of time it took for logoff to happen for some Insiders in the last few builds.
  • We fixed an issue resulting in some Insiders finding that their screens became dimmer after upgrading to the last few builds.

Known issues

  • We’re working on a fix for an issue where some Microsoft Store games protected with Easy Anti-Cheat may fail to launch.
  • We’re working on a fix for an issue causing some systems to crash with a HYPERVISOR_ERROR bugcheck.
  • We’re looking into reports of the update process hanging for extended periods of time when attempting to install a new build.
  • We’re aware of an issue where Task Manager reports 0.00 GHz CPU usage in the Performance tab.
  • We’re working to fine tune the tile animations in Start to avoid flashes of color.
  • We’re investigating reports that sleep is not working for some Insiders

In addition to this new build, Microsoft also announced today that it has started rolling out a new Windows Search experience on Windows 10 version 1809 and newer. The new two-column layout will be available in markets that enable Quick Searches, and you can learn more information in our separate post.
