After rolling out 20H2 Preview Build to the Beta channel, Microsoft releases Windows 10 Insider Preview Build 20170 to the Dev Channel. In comparison with the previous build 20161 released in the first week of July, this build is a minor one.
The build comes with a new improved Sound Settings experience, a fluent Settings icon, an experimental implementation of Transport Layer Security (TLS) 1.3 along with bug fixes. Below is the full changelog of the build:
- 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 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.
However, it comes with some known issues which are as follows:
- 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.
Microsoft also noted that Windows Insiders on AMD processors won’t be able to install the build because there is a bug impacting the overall usability and mentioned that it will be fixed in the next flight. Moreover, you can know more about it in the release notes at Windows Blog.
