Windows 10: How to submit a Non PNP driver for WHQL that the class is unknown?

Hello,


I have a non PNP driver, it’s a kernel service not for a hardware device. I know it needs INF file to submit the WHQL, but it hard for me to find a proper “class” for my driver, how can I specify the “Class” and “ClassGuid” in the INF file for the driver? Can I use “Class=unknown”?


Thanks,

Mark

Hotfix drivers will contain either or both game or bug fixes without having gone through the WHQL process.

As far as WHQL goes to many get hung up on whether the driver is or not. There are also quite a few that believe that Microsoft does extensive testing on drivers in order for them to be WHQL. That couldn't be further from the truth. In order for a driver to be called WHQL it is up to the hardware manufacture to use this,

and do the testing themselves, and the submit the log(s) to Microsoft for verification.

Some also confuse WHQL with a driver being digitally signed. A driver can be both non-WHQL and digitally signed,

That means nVidia only submitted this for WHQL testing on those GPUs. Which is why those are the only GPUs supported by the WHQL version. This driver is identical to the Beta version, it is just WHQL certified for those GPUs.

Thanks, I usually just download the main driver and have had no problems at all. Just wondered what Hot Fix meant.
