Microsoft has released WSL 2.9.12, a pre-release version of the Windows Subsystem for Linux that aims to enhance the native wslc container tool by aligning it with Docker's CLI functionalities through new commands. Key improvements include addressing user complaints about file ownership visibility and a networking issue that previously resulted in DNS configurations being lost. This update adds useful features for Docker users and includes four installers, although it is primarily intended for developers wanting to test the latest changes rather than for production use. Overall, the release represents a significant step towards improving container support on Windows while also providing fixes for existing issues

WSL 2.9.12 Pre-Release Brings Docker Parity to wslc

Microsoft has shipped WSL 2.9.12, a pre-release focused on making its native wslc container tool behave like the Docker CLI through new flags like --size, --all, and --all-tags. Alongside the CLI polish, it lands real fixes for the parts people actually complain about, most notably a virtiofs ownership bug that made every file look root-owned, plus a networking fix that left /mnt/wsl/resolv.conf without nameservers. Four installers are available now, though it rides the pre-release channel so expect some rough edges. It's a solid move toward containers-on-Windows maturing, but as with any pre-release it's really for developers who want to test things early.
