Install and Run Linux distribution Software on Windows Subsystem for Linux (WSL)

Microsoft Released Windows 10 Insider Preview Build 18917 (20H1) to Windows Insiders in the Fast ring.

What is Windows Subsystem for Linux 2 (WSL2)?

WSL 2 is a new version of the architecture that powers the Windows Subsystem for Linux to run ELF64 Linux binaries on Windows. 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!

What’s new in 18917

  • New download throttling options for Delivery Optimization
  • Microsoft 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 network. That’s why they added a new option to throttle the bandwidth used by
  • Delivery Optimization as an absolute value. You can set this separately for Foreground downloads (downloads that you initiate from Windows Store for example) or background downloads. This option already exists for IT Pros who use Group Policies or MDM policies to configure Delivery Optimization. In this build, Microsoft made it easier to set via the settings page.

You can access this option via Settings > Update & Security > Delivery Optimization > Advanced Options

Following General changes, improvements, and fixes for system.

  • Fixed an issue where some users experienced a 0x8007000E error code while downloading the build due to high RAM consumption.
  • Fixed an issue where users couldn’t use the desktop Features on Demand “add a feature” option.

Access your Linux network applications with a dynamic IP address in initial builds

WSL 2 includes a huge architecture change using virtualization technology, and Microsoft is still working on improving the networking support.

Since WSL 2 now runs in a virtual machine, you will need to use that VM’s IP address to access Linux networking applications from Windows, and vice versa you will need the Windows host’s IP address to access Windows networking applications from Linux.

Microsoft aim to include the ability for WSL 2 to access network applications with localhost as soon as possible. You can find full details and documentation here.
