Prior to DirectX 10, DirectX runtime was designed to be backward compatible with older drivers, meaning that newer versions of the APIs were designed to interoperate with older drivers written against a previous version's DDI. The application programmer had to query the available hardware capabilities using a complex system of "cap bits" each ...
It only supports "pluggable software device" like DirectX 9.0. DirectX 7.1 is the last version having RGB software rendering support. Ironically, .NET Framework 3.0 or greater shipped with a pluggable DirectX 9.0 RGB device RGB9RAST for WPF compatibility runs well on Windows 98 or later, while WPF only supports Windows XP SP2 or later.
Microsoft DirectX, a set of standard gaming APIs, stopped being updated on Windows 95 at version 8.0a. [17] It also stopped being updated on Windows 98 and Me after the release of Windows Vista in 2006, making DirectX 9.0c the last version of DirectX to support these operating systems.
Intel introduced DirectX 10 for the X3100 and X3500 GPUs in the Vista 15.9 drivers in 2008, though any release of DX10 drivers for the X3000 is uncertain. WDDM 1.1 is supported by X3100 but DXVA-HD is not. OpenGL 2.0 support is available since Vista 15.11 drivers [63] and XP 14.36 drivers. [64] Windows 8 ships with a driver for the X3100. [65]

9.0c (Oct 2006) (optional) It is possible to install the MS-DOS variants 7.0 and 7.1 without the graphics user interface of Windows. If an independent installation of both, DOS and Windows is desired, DOS ought to be installed prior to Windows, at the start of a small partition.
DirectX 9.0L is not for XP, and it doesn't support SM 4.0. It's Vista only - the Aero Glass interface runs on it, for example. Really? I had no idea. Seeing as DirectX 9.0L is going to be the final revision of the DirectX 9 API, and DX 10 is a rather large code rewrite, I assumed that DX 9.0L was gooing to be for XP...
Direct3D 9Ex, in conjunction with DirectX 9 class WDDM drivers allows graphics memory to be virtualized and paged out to system memory, allows graphics operations to be interrupted and scheduled and allow DirectX surfaces to be shared across processes. [41] Direct3D 9Ex was previously known as version 1.0 of Windows Graphics Foundation (WGF).
