@462, you are right, Microsoft updates are quite badly tested right now hopefully it will improve in the future.
You can update windows in "Parameters": https://support.microsoft.com/en-us/windows/update-windows-3c5ae7fc-9fb6-9af1-1984-b5e0412c556a#WindowsVersion=Windows_10
If you have not disabled updates, it should update automatically in the next few days
Be aware that sometimes, the update can take some hours/days to appear (Microsoft are distributing updates gradually).
