Microsoft has released Windows 10 Insider Preview Build 20170 to Insiders in the Dev Channel (previously known as the Fast ring). Today's build arrives after quite a feature-heavy release of Windows 10 Build 20161 that brought theme-aware Start menu.

Windows 10 2021 Preview Build 20170 isn't being offered to Insiders who are running devices that have AMD processors "due to a bug impacting overall usability of these PCs." Microsoft said that the issue should be resolved by the next flight.

Windows 10 Build 20190 Is Out with New Post-Update Experience

Note that Microsoft isn't matching new builds with specific versions of the operating system anymore. However, many of these features that are currently being tested are likely to be introduced with the release of Windows 10 21H1.

Here is the changelog of Windows 10 2021 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!

Improving search from the taskbar in Windows 10

We’ve recently unveiled two improvements to the search bar in Windows that make it even easier to find what you need.

Click on Search in the taskbar or press the Windows key + S to view an updated design for Search Home. A new two-column layout offers easy readability, as well as fast access to Quick Searches, where you can see local weather, top news, and more helpful info. To find other web results or navigate directly to a website, just type in the search bar like normal.

The new layout is available in markets that enable Quick Searches, including the United States, Australia, Canada, China, France, Germany, India, Japan, Mexico, Spain, and the UK.

In addition, the Windows search bar now supports web search for Dutch-speaking customers in the Netherlands. Users with their Windows region set to Netherlands and their language set to Dutch can now search the web from their search bar without using a browser. Previously the feature was limited to English-speaking users in the region.

We welcome your feedback on these updates. You can share your comments by clicking the feedback button on Search Home.

Note: This is a server-side rollout and will be visible to those running Windows 10 version 1809 up to the latest Dev Channel build.

Updates for developers

The Windows SDK is now flighting continuously with the Dev Channel. Whenever a new OS is flighted to the Dev Channel, the corresponding SDK will also be flighted. You can always install the latest Insider SDK from aka.ms/InsiderSDK. SDK flights will be archived in Flight Hub along with OS flights.

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! windows 10 2021
  • 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.
