Because the driver you have is not WHQL signed, some people prefer or need a version that is WHQL'd so it is offered as a choice.
that is understandable apart from the fact that the driver updater
already know I am running on a non whql driver, which would have been
installed be choice as the updater doesn't offer non-whql drivers. If
the whql driver was more recent than the non-whql driver , that would be
understandable, but it is not.
In otherwords, by running the non whql driver I have already indicated I
am happy to do so!
Maybe the updater logic could be improved.
