There are two ways of doing this. First off, leave UAC turned on and not provide the user with local administrative privileges. In the image below, the blue and yellow shield icon represents an action that UAC will ask for elevation of privilege before continuing.
In environments that have to turn off UAC or provide end users with administrative rights, we can use Group Policy.
- Crate a GPO and scope it based on the logged on user, not the computer.
- Expand User Configuration / Policies / Administrative Templates / Network / Network Connections
- Enable the policy called Prohibit access to properties of a LAN connection.
This will prevent the user from seeing the above screen.
