The “Feature Update Deferral” option box has disappeared on my v1909 as described in the scenario that Woody wrote on the 11/7/2019 in Computerworld. KB 4522355 fix seems to apply only to v1903.
I have been trying to set up a new w10 pro desktop that has 1909 installed. Not knowing anything about the convoluted update process in w10, I used pkcano’s excellent guide. I left the Quality update deferral at 0 but changed the Feature update deferral to 365 (I think) from 0.
A day later, poof – the Feature Update Deferral option disappeared; the Quality update deferral remains as I did not change it from 0.
Searching on the problem I ran across the Computerworld article which addresses v1903, not 1909.
There is a similar setting in the Group Policy Setting under Win Update for Business (which also has a Semi Channel option that I thought was gone). Advice seems to be not to use Group Policy settings for deferrals. Anyway, if I set it to less than 365, it may not override the 365 setting.
Any suggestions other than reinstalling Windows – a rather drastic step for a minor problem?
