Hi moobot83,
My name is ZyloxDragon, and I understand you are having issues with the "Network Proxy Settings in Internet Explorer" for Windows 10... or some other copy/paste response that Microsoft uses.
I know in the past you could set the settings you needed with a group policy using MMC, but it looks like they took it out of the default installation for some reason. I'm guessing maybe they moved the settings over to the server sides. This link might help though with adding the registry keys for it, but I'm not sure if you need to add the administrative templates it talks about.
My system uses Windows 10 Pro, and looking at my registry, it does show the ProxyEnable key, but not the other ones unless I enable a Proxy in IE. It may be worth a shot to try it though, just make a system restore point first.

If anything, you can have your computer run a bat file on startup to install the listed registry keys and your settings using reg add from the command prompt.
Edit:
I forgot, if the keys are already set when you go into the registry, you should be able to export the registry keys you need, and have a bat file written to import them. That way there's no typos to worry about. It's been a few years since I played with this type of stuff.
