The moved PB updates into WU and they recently added the branch choice - although, a choice of 1 isn't much of a choice.
Things are in flux - 9926 was when Win10 broke away from Win8 and every other Windows.
Things will settle down in the next releases as they merge all of the stuff into one package ... then they'll break stuff again!
I think it will be great when it's RTM, but that's at least 8 months away.
as far as the updates go; Im getting some message about there being a update; but; it errors out for me as well when trying to install it.
It's up to you to make sure MS is aware of your hardware and the issue.
