Microsoft has released an updated version of DirectX for June, although it isn't clear whether the update is just for DirectX 9.0c or for DirectX 10 on Vista as well. Regardless of this, it is still recommended that Vista users update their systems because Vista will benefit from any DirectX 9.0c fixes when playing DirectX 9 games. The web installer is only for Windows 2000, Windows XP and Windows Server 2003 (both 32-bit and 64-bit versions), whilst the redistributable version will also work with Vista.
