some colleagues reported that they are not receiving the update messages every 3 hours like i told them in the info mail.
About user notification, we should check if these clients are focus on tasks, Windows offers lots of ways to minimize distractions so it's easier to focus on tasks. Please navigate to Action Center and check if the status is Focus assist.
Some machine have not install 21H2, it means some clients have installed, is not it? Could we know it is deploy by task sequence? if so, please check smsts.log between the the normal client and the issued client. If the update is deployed by feature update, we could check UpdatesDeployment.log.
