[edit] OpenGL Installation on Windows
The Microsoft Windows operating system following Windows 95 all come with an OpenGL implementation bundled (usually version 1.4). However, if you installed (or updated) the drivers for your graphics card it's probable that you're using your board's manufacturer own implementation of OpenGL. The OpenGL library can usually be found by the name OpenGL32.dll under the \system32 folder, located in your system's root folder (usually c:\windows).
[edit] Headers
Headers compatible with OpenGL are bundled with most compilers. The header's versions may not be fully updated to your running implementation of OpenGL. If so, the new functions must be linked manually using the OpenGL's extension system.
