Sadly, this story is wrong and stems from a misunderstanding of how this feature works. The OS bootstraps these suggested apps from a configuration hosted by Microsoft servers, not anything present in your ISO. (e.g. https://twitter.com/thurrott/status/1122847063312613377)
I installed Windows as early as last month (in a VM) and still got Candy Crush. This is probably because my ISO image was not fully up to date.
I was not aware of this change but it is greatly appreciated. I can no longer modify the parent comment but if dang or anyone else with permission wants to please feel free.
No need for a new litmus test, though solving the problem of Edge opening MSN ads after updating would probably buy some goodwill.
