Downloading random system components from the Internet is a really, really
bad idea from a security perspective. The Microsoft DirectX Web Installer is
really the best place to go to make sure you are getting real bits instead
of rootkits and should include everything and the kitchen sink with respect
to the DirectX SDK optional components like D3DX9, D3DX10, XACT, XINPUT,
etc..
