To the best of my knowledge Windows 7 comes loaded with DX 11. I ran the DirectXdianostic tool and found the following info:

Now here’s the twist. When I ran the Intel diagnostic software to update my drivers, it gave the following result:

    HiDid you tried pcwizzardhttp://www.cpuid.com/softwares/pc-wizard.html

    also there is a microsoft hotfix

    The DirectX Diagnostics Tool incorrectly reports DirectX 11 devices as DirectX 10.1 devices on a computer that is running Windows 7 or Windows Server 2008 R2

    When you run the DirectX Diagnostics Tool (Dxdiag.exe) on a computer that is running Windows 7 or Windows Server 2008 R2, the diagnostic tool incorrectly reports a DirectX 11 device as a DirectX 10.1 device. This incorrect version information is shown in the DDI field on the Display tab. This problem is only a reporting error. This problem does not affect the DirectX 11 hardware or software functionality of the graphics card.
