Can you elaborate a little more ?

When I use wglMakeCurrent could you tell me if the new current context keep the same value of the previous one for the modelview matrix, GL_DEPTH_TEST, textures are still available or vertex buffer object as well ?

States such as the current modelview matrix, material state, enables, ... won't be shared. Every context has it's own seperate state.

Textures, shaders, VBOs, display lists (in general: data objects) are seperate per default, but you can share them between contexts with wglShareLists.
