Microsoft has surprised many Linux developers in recent years. Surprises included adding the Bash shell to Windows or the native OpenSSH in Windows 10 and even Ubuntu, SUSE Linux and Fedora in the Windows Store. Microsoft goes further and plans to deliver a full Linux kernel directly under Windows 10.
"Starting with Windows Insiders Builds this summer, we will add our own custom Linux kernel, the latest version of the Windows Subsystem for Linux (WSL)," said Microsoft program manager Jack Hammons. "The kernel itself will initially be based on version 4.19, the latest stable version of Linux. The kernel is redesigned to name new, stable, long-term versions to ensure that the WSL kernel always has the latest Linux quality.
The integration of Linux into Windows 1
For developers, the performance of the Microsoft Linux subsystem should be significantly improved on Windows. Microsoft also promises to update this kernel through Windows Update. It will be completely open source, giving developers the ability to build their own WSL kernel and contribute to changes.
Microsoft today also announced Windows Terminal, a new command line app for Windows. It is designed as a central location for accessing environments such as PowerShell, Cmd, and the Windows Subsystem for Linux (WSL).
