 You can also specify user SIDs here to force files created by a user to belong

+LXSS ("Ubuntu on Windows" / "Windows Subsystem for Linux")

+The driver will passthrough Linux metadata to recent versions of LXSS, but you
+will have to let Windows that you wish to do this. From a Bash prompt on Windows,
+edit `/etc/wsl.conf` to look like the following:
