Which command in the context of network configuration shows the existing proxy settings?

The command "netsh winhttp show proxy" is specifically designed to display the current proxy settings for Windows applications that use WinHTTP. This command provides detailed information about any configured proxy settings, including automatic configuration scripts if they are applied.

The command operates within the context of Windows' networking command-line interface, allowing administrators to check and verify proxy configurations swiftly and accurately, which is crucial for troubleshooting network connectivity issues, especially in environments where proxies are frequently used to control internet access or direct web traffic.

Other options, while related to network settings, do not specifically pertain to viewing proxy configurations. For instance, "show current proxy" does not align with standard command-line syntax used in Windows and would not yield any results. "Display active connections" refers to network connections without any focus on proxy settings, and "set proxy settings" is used for changing the proxy configuration rather than displaying the existing settings. Thus, the chosen command is the only one that effectively fulfills the requirement to show existing proxy settings.
