Windows - Technically how does the ZApp Enforce the Proxy settings?


I’m currently working for a client that is using the ZApp with the Enforce Proxy as Forwarding Profile Method.

From my understanding and what I have been told, with this parameter, the ZApp is only forcing the proxypac file and nothing else.
But technically, how does it enforce it ? Indeed, It seems to not modify the proxy settings on the control pannel or in the registry of the current user.

Kind regards,
