RE: the tip at end of this post: Insider Announcing Windows 10 Insider Preview Build 14986 for PC - Page 27 - Windows 10 Forums
Hadn't noticed this earlier:
I had EnableUUPScan and SupportsUUP in registry on one machine set to 0 to receive ESD upgrade instead of UUP before I upgraded it from 14971 to 14986. Got 14986 ESD, everything as I wanted.
Checking the registry now those values were reset by upgrade to default 1 (UUP instead of ESD). Had to manually change them back to 0 to get ESD of the next build, too.
