Checking Digital Signatures with the File Signature Verification Tool
The Dxdiag tool identifies problems with DirectX hardware and tells you whether that hardware has passed the WHQL testing regimen and has been signed digitally. However, it does not test the device drivers that are not associated with DirectX devices. To scan your computer and identify any unsigned drivers, you should use the File Signature Verification (Sigverif) tool.
