// Old windows version query APIs lie about the version number. There's no replacement
// API, and instead applications are supposed to queriy about capabilities instead of
// relying on operating system version numbers.
//
// Since we want to actually know the version number for debugging purposes, we need
// to use roundabout ways to fetch the information.
//
// The registry contains some useful strings, which we print out if the keys
// are available. The current official way to get version number is to look at a
// system DLL file and read its version number, so we do that too, in case the
// registry becomes unreliable in the future.
//
// If the DLL method fails, we simply don't print out anything about it.
// The minimal output from this function is "Windows Product: Unknown, Release: Unknown"
