Which web server software is created by Microsoft and supports HTTP, HTTP/2, and HTTPS?

The correct answer is Internet Information Services (IIS), which is a web server software developed by Microsoft. It is designed to host websites and serve web applications, supporting various protocols including HTTP, HTTP/2, and HTTPS. This capability allows IIS to handle modern web traffic efficiently and securely, enabling features like SSL/TLS for encrypted connections through HTTPS.

IIS is tightly integrated with the Windows operating system, providing a user-friendly interface for configuration and management through tools like the IIS Manager. This integration allows for easy deployment of web applications built on the .NET framework and offers a variety of built-in features, such as application pools, security settings, and logging mechanisms, which help maintain the performance and security of hosted applications.

In contrast, Apache and Nginx are open-source web servers that run on various operating systems, while Lighttpd is another lightweight option tailored for high-performance environments. However, none of these options are developed by Microsoft, and they may not provide the same level of integration with Windows features as IIS does.
