how to freeze status

I am still a bit confused on how to configure Returnil to freeze the current system with respect to system protection on and Session Lock.
My understanding was that Session Lock is only for the current session with the permanent solution being system protection. But my experience is that each time I enable system protection,it is off after reboot.
This is not a big deal if I am the first to boot up the pc in the morning but if I want to "freeze" a pc for guests, it defeats the purpose. I am sure that I am overlooking the proper set up.
Can anybody please assist me?

 

Figured it out myself - I used the right click/ enable function but this only starts the session lock. Need to actually use the change function with initial reboot.

Click OK.

After rebooting computer - you should have permanent protection until you manually turn it off.
