I understand what you've communicated thus far. Disabling Windows Update, uninstalling the 3x drivers you've mentioned, and then rebooting, does not result in any different/original drivers being reinstalled after the reboot. The update "6/19 update" is not automagically uninstalled as a result of removing those drivers.
If you could post the KB number of the update that you're saying is now pending, then I could attempt to make sense of the fix that you've described.
Thank you.
