Command
$ netsh winhttp show proxy

02What it does

WinHTTP is the proxy that system services and many CLI tools use; it is separate from the per-user proxy in Settings. `netsh winhttp show proxy` reveals whether a proxy is configured and what it points to. Companies often set this on managed machines, and leftover values can silently break downloads and updates.
