Yes.  Otherwise console windows appear for everything.

CreateProcessW is *the* way to create a process on Windows.
It has flags to control whether a window is shown, and we
intentionally set them to not show the window.

The `cmd /c` workaround should be sufficient, but it wouldn't be
hard to add an option to the execute_process command to allow
the window to be shown.
