I’m starting using Kali by WSL. Since WSL installs distros to C:\ by default, sadly I’m pretty tough on my C:, so after initialization(create account), I…
1.Exported kali to D:\WSL\backup
2.Unregistered kali on WSL
3.Imported D:\WSL\backup\XXX.tar to D:\WSL\kali
Then I checked that kali was well imported, but with ROOT user logging in by default.
I have checked group file under etc folder after importation, my account was shown like
adm:x:4:kira
Now the qurstion is: how could I change kali’s default user in such condition? 
I googled solutions but seems didn’t work for me. Guide me to solution please if there’s any.
Thanks a lot.
