Microsoft has released Windows 10 Insider Preview Build 20246 to Windows insider in the dev channel.

Announcing Windows 10 Insider Preview Build 20246

Hello Windows Insiders, today we’re releasing Windows 10 Insider Preview Build 20246 to Windows Insiders in the Dev Channel. Starting with today’s build, Windows Insiders will notice that the name of the branch we are releasing builds from has changed to FE_RELEASE. Just like we did  back in May when we released builds from the MN_RELEASE branch, we are practicing our ability to change which branch flight builds from. 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. As a result of the switch to the FE_RELEASE branch, Insiders will notice that some features like the updated emoji picker, redesigned touch keyboard, voice typing, theme-aware splash screens, and others have been removed temporarily. We look to bring these features back to Insiders in the future. As an important reminder – builds from the FE_RELEASE branch are not matched to a specific Windows 10 release.

Other updates for Insiders

• Starting soon, the preview experience of the Calendar app will be removed in an upcoming update and return to its classic look and feel. Windows Insiders will see a pop-up notifying them of the changes to the preview experience. No action is needed at this time.  We appreciate all your great ideas and are excited to continue building the best Calendar experience.

Updates for developers

The  Windows SDK is now flighting continuously with the Dev Channel. Whenever a new OS build 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

• We added automatic Linux distro installation to the wsl.exe --install command! This means that users who wish to install the Windows Subsystem for Linux quickly can just type in wsl.exe –install into the command line and then will have a fully set up WSL instance ready to go, including their Linux distro of choice.

Fixes

• We fixed an issue that could result in the Pick Time button in the Windows Update dialog not doing anything.
• We fixed an issue where hovering over a thumbnail in Task View would display an unexpected border around the item.
• We fixed an issue where chkdsk could appear to be stuck at 100% due to not printing the message saying it was done.
• We fixed an issue that could result in a crash when disconnecting certain audio devices while playing audio in recent builds.
• We fixed an issue where the Windows Update page in Settings could fail to load if connected to a Wi-Fi network with no internet connection.
• We fixed an issue resulting in Settings crashing sometimes when clicking the Update and Security category.
• We fixed an issue resulting in Storage Settings unexpectedly showing incorrect category sizes (a higher number than what was visible in File Explorer).
• We fixed an issue that could lead to a crash when managing partition size in Storage Settings.
• We fixed an issue that stopped GPU compute scenarios such as CUDA and DirectML not working for some users inside of the Windows Subsystem for Linux.
