interface IDXGIAdapter1 : public IDXGIAdapter
This interface is not supported by DXGI 1.0, which shipped in Windows Vista and Windows Server 2008. DXGI 1.1 support is required, which is available on Windows 7, Windows Server 2008 R2, and as an update to Windows Vista with Service Pack 2 (SP2) (KB 971644) and Windows Server 2008 (KB 971512).
A display sub-system is often referred to as a video card, however, on some machines the display sub-system is part of the mother board.
To enumerate the display sub-systems, use IDXGIFactory1::EnumAdapters1. To get an interface to the adapter for a particular device, use IDXGIDevice::GetAdapter. To create a software adapter, use IDXGIFactory::CreateSoftwareAdapter.
