The July's monthly quality rollup (KB4025336) failed to install IE 11 cumulative security update (KB4025252) first go-around; even though Windows Update history indicates KB4025336 as successfully installed. Second go-around was successful. This might have been an isolated incident, however others might want to check that Internet Explorer 11 has the most recent (KB4025252) cumulative security update installed since you won't notice unless you check IE 11, or when you run Windows Update again and KB4025336 pops up.
