Where do proxy settings come from?

Question

Windows

Good day!
At the enterprise we refuse Microsoft TMG. Gradually I clean up the tails of those who climb through TMG. The detection of settings through the WPAD file has been configured.
In the logs on TMG (10.78.0.1 srvtmg) I see how my Outlook is trying to establish a connection through port 8080 with TMG.
I can't figure out where the proxy settings come from.
There is no wpad entry in the DNS:

In the DHCP zone, the wpad settings saw out:

Client ip settings:

Netsh winhttp:

IE Connection:

TCPView:

How else can proxy settings for outlook be taken and why?

Answer 1

And what is so little smeared?

Answer 2

You can also push proxy settings directly through the GPU, but it seems that the "proxy server" checkbox in IE is grayed out, which is not visible on your screen.

Answer 3

Maybe the proxy is updated when the group policy is updated?
