I have my updates on Windows 10 Education set to the Semi-Annual Channel and the defer time for both feature updates as well as quality updates are set to 0 days.
Despite this I'm stuck at Version 1709 (Fall creators update) although according to this document from Microsoft Version 1803 is available since 10 July 2018 on the Semi-Annual Channel.
Furthermore I have noticed that Windows starts downloading Version 1803 if I stay on the Semi-Annual Channel and set the defer times to 1 day which makes no sense to me but at least shows that my system seems to have no general incompatibility with 1803.
Therefore I have two question:
- What could be a reason that I don't get update 1803? Is there anything besides the update channel and defer time that influences this?
- How can a higher number of update defer days lead to the installation of new updates?
Just to clarify: I'm not asking how I can install update 1803 (I know that I can either force it by manually installing from the ISO or I can set the number of defer days to 1 and install it that way). Instead I'm interested in what could have prevented the update when defer days was set to 0 and why it is offered when I increase the number of defer days.
