How can I upgrade my OpenGL version?

Question

I need to develop by OpenGL 4.3. I installed OpenGL Extensions Viewer and it shows me that i have OpenGL 2.1. I tried to update my Graphics drivers from "Drivers Manager" under windows but it tells me that I have the latest version. I tried to update my processor driver too but uselessly I get the same message, that my driver is updated. So my questions are :

1. How can I upgrade my OpenGL version?

2. If it is impossible to upgrade my OpenGL version, is it possible to develop by OpenGL 4.3 even if my laptop doesn't support this recent version?

Any suggestion or solution will be so welcome. Thanks

As far as I know you'd have to swap your graphics card for a new one to take advantage of later versions of OpenGL (since your current card is quite far behind).

I don't think you can develop for later versions unless you make your code backwards compatible and only use features from the OpenGL version that your laptop supports. If you are mainly working with OpenGL development (as opposed to making a game or whatever) that would clearly defeat the purpose.
