Microsoft is adding its own open-sourced Linux kernel to Windows 10 to improve performance of Windows Subsystem on Linux.
Microsoft has done a few custom Linux projects over the years. There was a Linux-based OS for datacenter network switches and a Linux-based microcontroller OS that it built for its Azure Sphere secure embedded service. And now we know about one more Microsoft-developed Linux project coming soon. Today at Day 1 of its Build developer conference, Microsoft revealed that it has created an in-house custom-built Linux kernel which it will be including as part of Windows 10, starting with Insider test builds delivered this summer. That kernel will provide the underpinnings for Microsoft’s Windows Subsystem for Linux (WSL) 2.
