    This article explains how our detection the Delta or Cumulative version of the patch is offered.

    HKLM" Key="SOFTWARE\Microsoft\Windows NT\CurrentVersion" Value="UBR" (Update Build Revision)
    • The Delta is offered if build version equals N-1. (N= Latest Build. Current build being offered minus one version level)
    • The full Cumulative update is offered if build version is N-2 or less.


    You will only be offered one or the other and never both.
