Oh dear. Which update? You can tell by clicking on Settings / Windows Update / Update History. If it’s 1703, that’s the one we’re talking about.
I think we are talking about 1703. But after the rollback, all I see are updates for the version I’m running, which is 1607. Also, the push shows up as repeated re-istallations of KB4049411 and KB 4033631. At least a half-dozen times.
