KB3194496 Won’t install. Gets to 99% then message: “We couldn’t complete the updates. Undoing changes” appears. After first failure ran Windows Update Troubleshooter, which appeared to make several repairs; however, when trying again to install the update, receive the same failure message. Overall, have tried installation now 4 times without success.
This Script will fix the install loop of cumulative update of KB3194496 (Cumulative Update 14393.222).
