Can I use `netsh` to diagnose the cause of winhttp_callback_status_request_error 12007?

Yes, `netsh` is a valuable tool. You can use commands like `netsh interface ipv4 show config` and `netsh interface ipv6 show config` to examine network adapter configurations. `netsh trace` can capture network traffic to identify potential issues. `netsh advfirewall firewall show rule` can help check firewall settings. `netsh winhttp show certificate` can diagnose certificate-related problems that could indirectly cause network errors.
