Is it possible to pass Windows HLK test for drivers compiled with WDK7.1

Question

We are facing critical situation about signing our drivers. I am wondering, is it possible to pass windows HLK test successfully for the drivers which are compiled with WDK 7.1

Because we were able to sign them using HCK but now after some bug fixes, the new version has to pass HLK test for windows 10 support, which can't !

Any advice is highly appreciated.

Thank you very much.

The answer is Yes.

The best thing you can do is just compile your drivers using wdk10 using VS2015 keep target OS as windows7 install it on windows10 and test it using HLK.

Or secondly you know that drivers are forward compatible if they are compiled for windows 7 they will work on windows 8.1 or windows 10 as well.

You just install your wdk7.1 compiled drivers on windows 10 OS. Then setup the client server for HLK and put the test for windows 10. After that whichever tests fails just read the errors and solve them.

Some modifications will be there if you want to give support for windows 10 OS Ex: NonPagedPool should be replaced with NonPagedPoolNx etc.

But yes you need to change the code according to errors you are getting on test fails and fix them on your own there is no easy way.

Yup there will be lot of work but that is possible for sure, I have done that for PCI serial port drivers.
