Ok, I'm convinced, just removed 2791 and 5719.
Not hit by any of the problems, but followed the instructions to revert, in case of some future defects appearing.
Uninstalling the updates (on several laptops) went well (seemingly so far).
I took the cautionary path as well. Uninstalled KB2975719 and KB2982791 with no apparent issues.
Didn't have any of the others.
I just uninstalled those two as well, had not had any issues yet but figure better safe than sorry - if they pulled those updates, figure I don't need them on my computer.
I do still have them, I do use my PC for hours daily and no problems have appeared, so I think I will stick with them as long as my PC works!
