OpenGL and DirectX is present all Windows Systems. But the capability to execute particular extentions or using capabilities are depends on hardware. It’s possible to you query the particular feature and use the features. It differs from one machine to other.
You can get the device parameters in Direct using GetDeviceCaps function and other related Direct3D APIs. Please see the sample. http://www.codesampler.com/dx9src/dx9src_1.htm#dx9_initialization
You can know the device capabilities with glGetString.
