WSL Goes Open Source: Microsoft Releases Windows Subsystem for Linux Code

In a move that surprised many, Microsoft announced that the Windows Subsystem for Linux (WSL) is now fully open source. Previously, some components were proprietary, but now the entire source code is available on GitHub under the MIT license.

For developers, this means full transparency: you can see exactly how WSL interacts with the Windows kernel and verify there are no hidden surprises. It also means community influence: you can submit patches and participate in feature discussions.

For startups and IT teams, this reduces vendor lock-in risks. If Microsoft ever changes direction, the community can maintain a fork. It also simplifies customizing WSL for CI/CD pipelines — you can tailor the environment to your exact needs.

Of course, questions remain: will Microsoft accept external pull requests as actively as with VS Code? Time will tell. But the move is a clear goodwill gesture.

METABYTE studio comment: Open sourcing WSL is great news for cross-platform development. We believe in transparency and control over tools, especially in cloud and hybrid environments.
