Fix Cumulative Update KB3194496 stuck or fail to install
After nearly a week of KB3194496 Windows update failing, I finally found a site that had a workaround or solution. Check out http://sihmar.com/2016/09/29/fix-cumulative-update-kb3194496-stuck-fail-install/ The first option worked for me. I used to be setup with the "Insider Program" but disabled it due to too many updates and issues. I presume one of the insider builds must have had an update to the xbox life scheduler jobs that must be causing this to fail. Good Luck, Ed
