No thanks, we want to pick a particular driver: Windows asks where we want to look - do we have a set of driver files, or is the driver already in the list of installed drivers?

In this case, we want to look at the list of drivers for this hardware that are already installed. When you're done experimenting, you can go back to the vendor-supplied driver by going through the same steps and choosing the vendor-supplied driver in the list of drivers.

Windows shows us a list of drivers that are already installed and usable for this hardware.

At this point you would expect to see two drivers listed: the vendor driver, and "High Definition Audio Device." (When I made this blog post, I was lazy, so I didn't bother to make a screenshot that showed two drivers.) To install the class driver, pick "High Definition Audio Device" and click "Next." "High Definition Audio Device" is a class driver, so you get this warning.

Talk to any tech person, read any forum, and at some point you’re sure to be told to update your drivers… And is it necessary to compulsively update your drivers? In very simple terms, drivers are computer programs that let Windows and your other applications interact with a hardware device.
