I’m guessing it’s specific to versions of the OS home, pró, etc. and maybe even device specific. I’m on a laptop and got the two updates, what about you?

    Well with the topic heading I have to agree. I removed KB3081449 and the constant explorer crashing stopped. It would crash regularly but randomly. Eventlogs were useless in determining the origin. Seems like it was just a patch bug as it happened after all updates were installed. I read elsewhere someone else had installed them and the crashing stopped. Seems to be the case with me as well so far. Its been more than 10 hours and no explorer crashes (new record previous was 3 horas).
