my 2016 servers are all 1607.
regarding the group policy setting
computer configuration/policies/administrative templates/windows components/windows update/windows update for business/ "select when preview builds and feature updates are received"
i would assume that if i enable this setting and put 365 in the "after a preview build or feature update is released, defer receiving it for this many days", it would check and grey out the "defer feature updates" checkbox in the updates settings gui. but it UNchecks it and greys it out. and i find update detection behavior to also be different than when i manually check the box in the settings gui. is this expected?
