In other words, use them at your own peril: there is no official release from Microsoft for running Direct X 10 or Direct X 11 on XP.
The latest version is 9.0c and unless there is a massive change of heart from Microsoft (no chance), this will always be the case.
Determine the Version of Direct X Installed on Your Computer Download Direct X Most Recent Release Use System Restore to Remove the Direct X Update Community Q&A Microsoft Direct X is a bundled set of Application Programming Interfaces (API) required for running many of the multimedia features in the Windows Operating System.
Users of Windows Vista and Windows 7 can quickly and easily update their system to the most recent Direct X release available from the Microsoft Website.
However, a game written specifically for Direct X 10 will generally not run on Direct X 9 or earlier.
It allows developers to standardise certain video display and audio files - this makes them easier to develop and run on different types of PCs (it is also used on consoles such as the Xbox). So, if a game was written for Direct X 9, it should run if you have Direct X 10 or Direct X 11 installed on your PC.
Each version of Direct X offers newer features and better rendering - in other words, prettier pictures that are more detailed and realistic (assuming your PC has the hardware to handle the heavier load).
Up until version 9.0c, the latest version of Direct X was generally available as a separate download from Microsoft.
Part of the reason that versions 10 and above are not available for Windows XP is due to an update in the more recent Operating Systems that use the new 'Windows Display Driver Model'.
It features in both Windows Vista and Windows 7 but not XP.
