Dxdiag Command Line options

dxdiag The DirectX Diagnostic Tool is one of the most useful utilities in Windows that was designed to fix DirectX-related (video) or sound related hardware problems.

The great thing about the tool, It provides a quick and easy access to most of the important information such as video and audio drivers that you need before you upgrade or reinstall your OS.

Creating a backup of those information is very useful especially on old laptops.

/x outfile – save XML information to the outfile and quit

/t outfile – save txt information to the outfile and quit

/whql:[on/off] – allow or do not allow dxdiag to check for WQHL digital signature


dxdiag /t dxdiag_backup.txt
