It is possible now to remove Server header from web.config starting from IIS 10.0 :

More details on how to remove all unwanted/unnecessary headers can be found here.

Please note that this hides server header from the "application", as do all the other approaches. If you e.g. reach some default page or an error page generated by the IIS itself or ASP.NET outside your application these rules won't apply. So ideally they should be on the root level in IIS and that sill may leave some error responses to the IIS itself.

There is a bug in IIS 10 that makes it sometimes show the header even with config. It should be fixed by now, but IIS/Windows has to be updated.
