Microsoft has released Windows 10 Build 20170 to the Dev channel (formerly Fast Ring). However, due to a bug in the OS, devices with AMD processors won't receive it. If you are lucky to get it, here's what's new in Windows 10 Build 20170.

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.

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!
• 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.

Fixes

• We fixed an issue resulting in flickering when resizing certain apps when snapped side by side in tablet mode.
• We fixed an issue when using an IME where holding down the mouse left click key would eventually lead to input hanging.
• We fixed an issue resulting in the master volume slider in Sound Settings not working after removing and re-pairing certain Bluetooth devices.
• 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.

The Fast ring, now known as Dev Channel, reflects the latest changes made to Windows code base. It is a work-in-progress, so the changes you see in Fast Ring releases may not appear in the upcoming feature update. Due to the changes coming to the Dev builds, it is possible that will see some of Windows 10X features on Desktop. Microsoft may want to roll out Windows 10X's features to test them with a larger number of devices. So we can expect to see some features which will never appear in stable Windows 10 versions on Desktop.

If you have configured your device to receive updates from the Fast Ring ring, open Settings - > Update & recovery and click on the Check for Updates button on the right. This will install the latest available Insider Preview of Windows 10.
