• Chasing the elusive upgrade for Win10 Pro v1803

    I have been doing some testing on my Win10 Pro v1803 machine. I wanted to see if the pulldown deferral settings in the Windows Update GUI under Advanced Settings really work.

    My Win10 Pro v1803 Windows Update Settings are as follows:
    + In the GUI, Semi Annual Channel, Feature Update deferral=365, Quality Update deferral=0, NO Pause.
    + In Group Policy under Windows Update\Configure Automatic Updates=Enabled, value=2 (notify download/install)
    + Fully up-to-date 2019-11 CU KB4525237 Build 17134,1130
    + wushowhide shows NO available updates.
    + There are no pending updates in the queue and it is reported “Up to date”.
    + There is NO “Download and install now” section/link because the updates are deferred thus not available.

    Testing:
    1. Set deferral=230 days, rebooted, wushowhide shows Feature Update 1809 (2019-1113)
    2. Set deferral=200 days, rebooted, wushowhide shows Feature Update 1809
    3. Set deferral=180 days, rebooted, wushowhide shows Feature Update 1809
    4. Set deferral=150 days, rebooted, wushowhide shows Feature Update 1809
    5. Set deferral=120 days, rebooted, wushowhide shows Feature Update 1903
    6. Returning to deferral=365 days, rebooted, wushowhide shows NO available updates.

    Observations:
    + Perhaps the 180 deferral for v1903 is too large by the 60-day one-time extension MS allowed for the change in updating (eliminating SAC (Targeted).
    + Settings between 230 days and 150 days deferral make v1809 available in wushowhide
    + A setting of 120 days deferral make v1903 available in wushowhide.
    + Returning to 365 days deferral eliminated the availability of the upgrades.
    + I did not run “Check for updates” because I did not want to do the upgrade at this time and that would have initiated the download/install.
    + Because I did not wait for the system to check for updates on its own, there were no available Feature Updates, so I did not see the “Download and install now” section.

    Conclusion: The deferrals seem to be working as expected.

    NOTE: the deferral days listed here are as of Dec. 8, 2019. If you are upgrading at a later time, add the appropriate number of days to the deferral periods going forward from 12/8/2019.
