How to create a DxDiag.xml file
Begin by holding the Windows key on your keyboard and press R. The Windows key is located between Ctrl and Alt on the left of most keyboards, and looks like a flag.
In the Run window, enter “dxdiag” into the Open box and press OK. If you are asked whether you “want to check if your drivers are digitally signed,” select Yes.
After a few seconds, the DirectX Diagnostic Tool will open and begin collecting your system information.
When it is done gathering information, click “Save All Information” at the bottom of the window. In the “Save as type” box, select XML File. Save the file to a location you can find again later, such as your Desktop.
You may now close the DirectX Diagnostic Tool window. Use the “Choose File” button below to find the file you just created and attach it to the survey.
