WSL2 is the second release of the Windows Subsystem for Linux, a feature of Windows which enables multiple Linux distributions and tools to run natively in Windows.

Super User is often the most appropriate Stack Exchange site for WSL2 questions, especially if you think your question is mostly related to Windows functionality. However, also consider whether some other Stack Exchange sites may be a better fit for your question:

  • If your question involves development on WSL2, or the use of development tools with WSL2, the programming expertise on Stack Overflow may be warranted.

  • If you think your question may be more related to Linux functionality, you may find the Unix & Linux Stack a better fit.

  • If you are using an Ubuntu distribution on WSL, and you think your question may be unique to Ubuntu functionality, then Ask Ubuntu provides access to Ubuntu expertise that may be able to help.

If you just aren't sure, then feel free to go ahead and ask here on Super User.

In all cases, it's recommended that you mention WSL2 in your question. Since the WSL2 and windows-subsystem-for-linux tags are sometimes used incorrectly, it is helpful to confirm that you are actually asking a WSL-related question.

We would also recommend confirming that you are using WSL2 by executing wsl -l -v from PowerShell or CMD. Often an older WSL1 distribution has not been updated to WSL2.

We also recommend that you include the version/build of Windows you are using in your question.
