Its especially unfortunate since KB4474419, the sha2 update for Windows Seven, defacto disabled updates for quite a few people with dualboot or encrypted system partitions in mid March.
The update fails and gets automatically reverted. I dont think you can get the monthly security updates without it, at least that was the case with the April rollout. Since its not immediately clear why the update fails, you can even now find quite a few people looking for help to diagnose the error online.
