Unfortunately most of the recommendations you will find online for removing the "Server" header in IIS will not work for IIS 8.0 and 8.5. I have found the only working option, and in my opinion, also the best, is to use an IIS Native-Code module.

Native-Code modules differ from the more common Managed modules, as they are written using the win32 APIs rather than ASP.NET. This means that they work for all requests (including static pages and images) rather than just requests that past though the ASP.NET pipeline. Using a Native-Code module, it is possible to remove unwanted headers at the very end of the request, meaning that you can remove headers (including the "Server" header) regardless of where they have been set.

Binaries and source code of an example Native-Code module for removing headers in IIS 7.0 to 8.5 are available in the following article.
