The latest Microsoft Windows 10 Technical Preview Build 9926 comes with the next iteration of Microsoft's gaming and multimedia API's DirectX 12. While DirectX 12 is now being shipped with Windows 10 Technical Preview builds, to experience it's visual and performance gains the graphic cards drivers and apps needs to be updated to make use of the new API, which should take some time to start appearing.

AMD amazed everybody by saying there will be no DirectX 12, and now Microsoft has disappointed users on older Windows version by making DirectX 11.2 EXCLUSIVE to Windows 8.1 and next-generation consoles. Making users on older Windows version feel more miserable, the new update features the ability to allow a game use both system RAM and graphics RAM to store textures, which will enable DirectX 11.2 games to vastly improve the resolution of textures displayed in-game.

However, this was later clarified with an official announcement that XNA was being discontinued not DirectX.

Now, adding more support to this suggestion, AMD's Vice President of Global Channel Sales - Roy Taylor has said there will be no DirectX12 at any time in the future during an interview given to a German magazine.

Fake bundles of DirectX 11 for Windows XP also took advantage of the situation to spread malware - Various genuine efforts also tried making a Windows XP port of DirectX 10 but are not being actively developed anymore.

To bring some relief to Windows XP users, Microsoft has now released an update to DirectX® End-User Runtime after a long time. This new release features updates to 9.0c and previous versions pushing the build version to 9.29.1973 offering better multimedia and gaming experience on users PC.
