Microsoft has made WSL Containers generally available, letting users run Linux containers on Windows through the Windows Subsystem for Linux. The feature installs via the wsl command and extends WSL beyond simply running Linux distributions, according to both Help Net Security and BleepingComputer.
The security-relevant detail comes from Help Net Security, which reports that the feature ships with administrative controls that allow IT teams to switch it off entirely or limit where container images can be pulled from. BleepingComputer confirms the rollout and the general availability but does not mention these governance options, so the two sources agree on the release while differing in the level of security detail provided.
For organizations adopting Linux containers on Windows, the ability to restrict image sources gives admins a way to reduce the risk of developers pulling from untrusted registries. The absence of that detail in one source does not contradict the other, but it highlights that the security controls are a notable part of the announcement rather than a universally reported one.
