Current Build vs. Current Build for Business in Windows 10 comes down to one check box in Windows Update Advanced Options:
Checking “Defer Upgrades” puts machine in Current Build for Business.
It can also be set with a GPO. Go to Computer Configuration > Administrative Templates > Windows Components> Windows Update and configure the “Defer Upgrade” policy. If you enable the setting, it puts machine into CBB.
