Hello Everyone, I have run into a strange issue when integrating 2018-06 Cumulative Update for Windows Server 2016 for x64-based Systems (KB4284833), when building Windows Server 2016 installer .iso. The starting base iso is version "en_windows_server_2016_updated_feb_2018_x64_dvd_11636692.iso" When integrating the update into wim via dism, it quickly gets to 100% and completes successfully, however after installing the image from the built iso, Windows Update downloads the Cumulative from the previous month (2018-05 Cumulative Update for Windows Server 2016 for x64-based Systems (KB4103720), even though KB4284833 states it supersedes the KB4103720 one. After integrating the update in dism into wim, I have also checked the present updates via /Get-Packages in the image and it is not there. I did a test with previous package from May (KB4103720) and it does integrate properly, is present on the Features as well as goes through the integration process slower, before getting to 100%. Do you Guys have any clues what could be happening? Is KB4284833 not integratable or has some issues? Thanks in advance. EDIT: Apparently, I have missed (KB4132216) which is required for (KB4284833) to proceed. The issue has now been solved.
