Windows 10 users will soon be getting the Creators Update, which brings many new capabilities to users who want to run Linux command line utilities in Windows 10 through its Windows Subsystem for Linux (WSL). Those who are trying WSL for the first time will get Ubuntu 16.04 by default instead of 14.04.
Mary Branscombe writes at The New Stack:
Ubuntu 16.04 will be installed by default if the Creators Update is the first time you’re using WSL on a PC. If you already have 14.04, Windows won’t update your distro. Turner says that’s because of the very strong feedback from the community that they didn’t want the update to be automatic). You can do an in-place upgrade using `sudo apt dist-upgrade`, if you want a clean 16.04 instance, use `lxrun /uninstall /full` to remove your Ubuntu instance and then reinstall it with `lxrun install.`
With this update you can now have more reliable SSH sessions in Ubuntu.
