Need Help Disabling the Multi User in Android 7

[Mazhar]

I wanted to disable the multi-user feature in Android in my both Motorola phones, one has Android 5.1 and other has Android 7. I have been successful in Android 5.1 phone through the CMD command using ADB tools, the command I ran is this to disable it:

db shell settings put global guest_user_enabled 0

Here is the source of this. And the result is this:

 

 

As you can see in above video the function does not respond at all.

 

Now the same command I am running in my Android 7 phone is not working and the user panel is same as it is, this is where I need your help, what wrong am I doing or is there any change in the command that is need to be done.
