The fundamental check in this package is effectively equivalent . But you can run custom Linux kernels with arbitrary version strings inside WSL2, so this check is fragile and unreliable. There's no 100% reliable solution that I'm aware of, but there's some additional indicators that strongly point to a Linux environment being WSL2: The environment variable is set. VS Code's launcher script uses this, though obviously programs may be running with sanitized environment variables so an absence of this doesn't guarantee that we're not WSL. The existence of some mountpoints and paths that are distro-independent. If any of these exist, we're probably in WSL (and probably not in a container)
