I'm afraid you won't get any further update for that hardware.
Anyway, just to be sure, you were using latest available windows platform version 1800.12?
Yep, I am fine with not getting update just sharing experience.
I can't remember exact version, but that driver was described as final because of legacy nature.
Sorry to hear about the support response. Actually, all these products are currently under the legacy support model and no additional driver releases are planned. For more information, please check: Legacy
