How to choose Windows 10 user account sync priority during setup?

I have 2 computers both running Windows 10, one of which is brand new.
When I setup the new computer, I signed in using Microsoft account, expecting the new computer to sync the settings from the old one. But instead, the new computer's default settings overwrote existing settings on the old computer, which is just dumb.
Because of some hardware issues, I've had to replace the new computer and setup a new one again. Now I really don't want the same thing happening again. So is there a way to make sure my new Windows 10 only receive settings from the old one?
