whql for tdi drivers for windows 10 1607

Hi Experts

For Windows 1607 and beyond when “secure boot” is enabled, you don’t
need to sign your driver at all. You sign your submission package to
the dashboard for attestation signing, and the package that comes back
is signed by Microsoft. This is not “cross-signing”. This is a
brand-new signature.

Alternatively, you can submit your package through the dashboard for the
full WHQL treatment. The resulting package is signed by Microsoft (not
“cross-signed”) and will work across the board.

Based on this we have a TDI driver which we submitted for attestation signing and got the signing.This works for secure boot enabled.

But if we submit for WHQL treatment then our driver can work on all previous OS as well.

Now my question is can our driver pass WHQL.
Can TDI drivers still be WHQL signed?

Searching online I can see vague references that TDI drivers will fail WHQL but their are no definate answers from Microsoft.

I have never known of a TDI,driver to be WHQL signed.

But so what? Atteststion sign the Win10 version, then do whatever you did before for install on other systems. Problem solved.
