title: How to set default user to root in WSL
body: <p>On my new laptop I've installed Ubuntu from the store. In the legacy version of WSL, i could change the default user to root by using </p>
  
  <p><code>lxrun /setdefaultuser root</code></p>
  
  <p>Apparently lxrun is only for the legacy version, is there a way to do this in the new WSL that is installed form the store? I looked at wslconfig but it appears that is just used for managing different distros.</p>
