Last night, Microsoft released a new Windows 10 20H1 Insider Preview build. Among the improvements is our first peek at Windows Subsystem for Linux 2.
“WSL 2 is a new version of the architecture that powers the Windows Subsystem for Linux to run ELF64 Linux binaries on Windows,” Microsoft’s Dona Sarkar writes. “This new architecture, which uses a real Linux kernel, changes how these Linux binaries interact with Windows and your computer’s hardware, but still provides the same user experience as in WSL 1 (the current widely available version). WSL 2 delivers a much faster file system performance and full system call compatibility, which lets you run more applications like Docker.”

New download throttling options for Delivery Optimization are also new in Windows 10 Insider Preview build 18917.
“We’ve heard from our users with very low connection speeds that setting download throttling as a percentage of available bandwidth isn’t providing enough relief in reducing the impact on their networks,” Sarkar explains. “That’s why we’ve added a new option to throttle the bandwidth used by Delivery Optimization as an absolute value.”
Build 18917 also includes improvements to Narrator’s data table reading capabilities, a more compact new Windows Ink Workspace experience, and numerous other changes, improvements, and fixes.
