This is the DirectX 9.0c control panel for Windows 98/ME/2000/XP/2003! Quite handy and a very small download as it is roughly 100 kb. Control panel with various attitude possibilities for Microsoft's DirectX 9.0c. for the installation one copies directx.cpl into the Windows/system32, afterwards the program can be called by system control. Alternatively it does doubleclicks to the file exactly the same.
Just click on the "directx.cpl" and you are good to go.
