WSL1 also doesn't show windows proceses in 'ps', only the WSL processes. For example:

    shawnz@ShawnsPC:/mnt/c/Users/shawn$ ps xwau
    USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
    root         1  0.0  0.0   8936   184 ?        Ssl  Nov17   0:00 /init
    root         6  0.0  0.0   8936    96 tty1     Ss   Nov17   0:00 /init
    shawnz       7  0.0  0.0  18588  2708 tty1     S    Nov17   0:00 -bash
    shawnz     252  0.0  0.0  18880  1984 tty1     R    18:04   0:00 ps xwau

But in your example, I can already see you have a init system and multiple users - neither of which will be needed in most cases.

The "init" process is just a stub used by WSL, it is not a "real" init system. And Cygwin also allows the creation of multiple users within the Cygwin environment, doesn't it? It's just a matter of populating /etc/passwd. If you want to use WSL1 with a single user then you could just set the default user to root.
