you no longer need Windows Insider preview for WSOL - its part of the creator's update. still has a beta tag but its available without having to use a full beta OS.
When did this change? as my home machine required me to move to insiders for WSL just on the weekend. (also the volume of spam they are sending to me now :|)
Creators update came out back in April. I think you need the Insiders Program right now to pick which Linux distro you want to install, normal way only gets you Ubuntu?
