See WinHttpGetDefaultProxyConfiguration function (Windows)[^].

Alternatively read the registry key that contains the Windows HTTP proxy settings. The key is

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\

and the value is stored as text in ProxyServer (source: How to configure client proxy server settings by using a registry file[^]).

Note that some applications (usually all browsers) allow setting their own proxy rather than using the one configured for the system. Then you have to read the configuration for those applications.
