Removing guest account on Android 6 upgrade

[moein_na]

Hi,
My tab s9 (8) had been upgraded to android 6 marshmallow recently,
Now on lockscreen there is a user fig which is a key to change user similar to what we saw later on common os such as linux, win or osx, and a guest account which is not removeable even from setting>users

I want to ask anyone khows how to remove this guest account?

Welcome to Android Central! Sorry, just want to clarify--do you have a Samsung Galaxy Tab S2? I'm not sure what you mean by tab s9 (8).
