It was once easily found in the familiar Add/Remove programs applet through control panel and clicking on windows components would reveal additional options installed by the the OS for specific functions or roles of the server to operate. Now, it's moved to server manager in Windows Server 2008.
Having the enhanced security applied to the browser by default on servers is a nice thing to have. Many of us however do use the browser on the server to find driver updates and other things we need to perform tasks.
