There was (and still is!) a great web site for this, letting you see where the various "Dial Up Networking" screens were in Windows: http://www.chasms.com/
What an amazing site. I was clicking through the advanced IPv4 settings on Windows 10 and clicking through the simulator for Windows XP and saw that they were exactly the same, beyond the different OS themes. So much overhaul for what network configuration looked like over the years, and the parts for experts are now deeply buried but unchanged.
