Microsoft’s Windows Subsystem for Linux is now open-source
Microsoft is making its Windows Subsystem for Linux (WSL) open-source today, opening up the code for community members to contribute to. After launching WSL for Windows 10 nearly nine years ago, it has been a multiyear effort at Microsoft to open-source the feature that enables a Linux environment within Windows.
“It has been a consistent request from the developer community for some time now,” says Windows chief Pavan Davuluri in an interview with The Verge. “It took us a little bit of time, because we needed to refactor the operating system to allow WSL to live in a standalone capacity that then allowed us to open-source the project and be able to have developers go and make contributions and for us to ingest those into the Windows pipeline and ship it at scale.”
The WSL code is now available on GitHub, allowing developers to download it and build it from source, participate in fixes, or even add new features. The WSL community hasn’t had access to Microsoft’s source code in the past, but that hasn’t stopped them from making contributions that have helped improve WSL over the years. Davuluri says he’s now expecting that developers will use the open-source project to help improve WSL performance, or for more integration into Linux services.
