OpenGL is an API, there isn't really any downloading it.

You'll need up-to-date header files.

You can find those here:
here

you may also want to check out the NeHe tutorials if you're just getting started.
It's a great place to learn.

Your compiler should have both include and library files. If not you can download them from your compiler site.
I'm sure every MSVC version have these files and also open source packages (mingw/gcc based) like CodeBlocks and Dev-C++.

why not ... [google] ?

OpenGL is a software interface to graphics hardware - ie, your graphics card be it an old ATI Rage, or a Top of the line nVidia GeForce 7800. If you have Microsoft Visual Studio, it already has a set of headers with it, and you can learn how to actually use these at http://nehe.gamedev.net.

It is not strictly a standalone graphics library, for best performance you need hardware that will support it, and in Windows, most hardware comes with OpenGL as part of the drivers. Just start searching on Google and OpenGL's Site.

Hope this will answer your questions.
