WSL containers now build and run Linux workloads on Windows

Containers power a large share of cloud-native applications, AI workloads, and testing and deployment pipelines. Developers working on Windows have long pulled in third-party software to build and run them. That step becomes optional with WSL containers, a feature that arrived at Microsoft Build 2026 and reached public preview in the pre-release version of the Windows Subsystem for Linux, build 2.9.3.
