Hi, @Izanagi76
Thank you for posting in Microsoft Q&A forum.
Yes, you can use the "Schedule Updates" feature to integrate recent cumulative updates into an existing Operating System Upgrade package for your Windows 11 image (version 24H2). This operation is supported, and the process for applying software updates is the same for both OS images and OS upgrade packages.
Before proceeding, ensure that you have the necessary prerequisites, including a software updates infrastructure, successfully synchronized software updates, and downloaded updates to the content library on the site server.
When you use the Schedule Updates feature, Configuration Manager will apply the selected software updates to the image and can redistribute the updated image to distribution points as needed.
