and it seems that I'm seeing some new reports that Win10 v1803 users are receiving KB4346084 as an automatic update or thru windows update (when using some affected Intel CPUs) instead of KB4100347. so it looks like KB4346084 is no longer a Catalog-only update and does replace KB4100347
yup - as with KB4465065 for v1809, KB4346084 for v1803 (the 2019-02 version) is also being delivered thru Windows Update after a recent WU metadata change this June and no longer being an MS Catalog only update
