How to get this update
Method 1: Windows Update
This update will be downloaded and installed automatically.
These are the updates that Windows Setup pulls down. It's what "checking for updates" is pulling down when you run setup.exe from within Windows. They aren't meant to be installed by the user.

Windows 10 Dynamic Update: This includes only updates to the setup process that occurs when one build of Windows 10 is trying to update to a new build of Windows 10 (i.e. 1511 to 1607).
