How to Lock Down Proxy Settings in Windows 11

This post shows students and new users how to lock down proxy settings and prevent users from changing them in Windows 11.

Some businesses setup proxy servers to control what leaves and enters the network. A proxy server is a network device that sits between your PC and the internet or external resources.

The proxy server makes requests for websites and services on behalf of the user’s computer. 

Once you configure a proxy server for your users to connect through, the users will also have the rights to change or bypass the proxy server by changing its settings in Internet Explorer.

If you don’t want to have users changing their proxy settings and want to restrict their internet connect through the proxy server, you can configure Windows machine proxy setting and lock it down.

Below is how to do that.
