About a week ago we posted how to install DirectX 10 in Windows XP. We also posted about the DirectX changer software which allows users to switch between DX9 and DX10 seamlessly in a Windows XP environment.
Version 1.1 of KM-Software DirectX Changer was released a few days ago. This version fixes a number of bugs and introduces the ability to change the active DirectX version without requiring a restart. If you are using DirectX 10 for Windows XP, this software is a must have since some games still do require DX9 and Windows XP wont be able to switch between DirectX versions automatically.
