It would be to know or can you one find the source code of the library OpenGL Windows version?
Thank you
The windows OpenGL library is not open source, so you won’t find the source for download. But you can download the reference implementation from SGI and the open source OpenGL implementation Mesa.
And to answer your other question: You get the most recent OpenGL implementation for your graphics card with the driver, there is no extra download.
Next time, please don’t make three topics for two very similar questions
