Research direction

Start at _win32_console.py line 403 and trace the call from _windows_renderer.py through io.py when the provider error is displayed. Reproduce the Windows 10 failure using the error path in base_coder.py, then verify that the original 404 error is reported without an uncaught OSError from console output.
