Windows 10 build 18917
Here are all the features and changes coming to the next version of Windows 10:
Windows Subsystem for Linux 2
Starting with build 18012, Windows 10 ships with Windows Subsystem for Linux 2, which is a new version of the feature that runs ELF64 Linux binaries.
This new architecture uses a real Linux kernel, and as a result it changes the way that Linux binaries interact with Windows 10 and the hardware while maintaining the same experience like in the previous version.
Microsoft says that this new version delivers a much faster file system performance and full system call compatibility, which lets you run more applications like Docker.
Delivery Optimization
After installing this flight, you’ll also notice that the Delivery Optimization settings page includes new settings to throttle the bandwidth as an absolute value. You can set this separately for Foreground downloads or background downloads.
Narrator
As part of the Narrator experience, starting with build 18917, Windows 10 is optimizing the information you hear with Narrator when navigating a table using table navigation commands.
Narrator now reads the header data first, followed by the cell data, followed by the row/column position for that cell. Additionally, Narrator only reads the headers when the headers have changed to focus on the content of the cell.
Windows Ink Workspace
In addition, this new 20H1 update, when opening the Windows Ink Workspace, you’ll notice a new interface, which is significantly smaller, and Windows 10 is now converging the whiteboarding experiences with a new direct link to the Microsoft Whiteboard app.
File Explorer
Finally, Windows 10 build 18917 includes an update for the File Explorer search experience to now be dark when used in dark theme.
Microsoft is listing the complete set of improvements, fixes, and known issues for Windows 10 Insider Preview build 18917 at the Windows Blog.
