Windows IIS all HTML returns blank

This is a magical phenomenon. Because the use of IIS has been n years, like to use it because it is readily available. It has not been used to debug the client program until today, since it was loaded with WINDOWS10. To put a static JSON data on it, save the need to build a Web application or something. The result is not getting what you want to get. So I began to suspect that my mind was not sober enough. But confirmed many times, still so. It really confuses me. Is there something? Start to cranky ... Eventually, StackOverflow Dafa solved the problem. The original IIS installation in WINDOWS10 has one more option: whether to host static content. It's so confusing, why? Anyway, it's finally done. Open the Control Panel program, and locate enable or disable Windows features. The list finds common HTTP features like Internet Information services-> World Wide Web services, which have a static content option to tick.

Wasted one hours of my time.
