How to Determine Current DirectX Version

To check the DirectX version, the most straightforward way is to use the dxdiag.exe utility from the search box or the "run" prompt in Windows (this is known to work for Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2).




After launching the DirectX Diagnostic utility, the version will be listed.
