LAN Connection Keeps Changing From Automatically Detect Settings To Proxy Server

This issue happened after I upgraded to Windows 10 from Windows 7 on my HP computer. We also have another older Dell computer, on which this issue did not occur after upgrading to Windows 10 from Windows 7. I followed advise from an IT technician provided about this issue with Windows 8.1 including editing the registry (Internet Settings and Default Connection Settings) and have no trouble accessing the internet. However, typically after every day or every other day (at most after three days) turning my computer on after being off overnight, the internet connection settings revert back from automatically detect settings to proxy server.

I do not use a proxy server and cannot access the internet when this occurs. This keeps happening even though I go back and reedit the register. What can be done to permanently fix this problem? I am currently using Internet Explorer 11 instead of Edge until Microsoft comes out with their update in early November that allows extensions. I use Norton 360 and cannot use this program with Edge until extensions are allowed, because of security on the internet.

Since this does not happen with the Dell computer, I checked the settings mentioned by the IT Technician and found that the following Internet Settings were not present in the registry: ProxyHttp.1 (or ProxyHttp1_1) and ProxyServer. Will it harm my HP computer if I delete these two from the registry so that the Internet Settings will be the same as those on the Dell computer, which as pointed out above does not have this problem? Also, for ProxyServer the IT technician indicated that there should be no value for this in the registry.
