Hi @TechUST ,
I also observed the same issue while upgrading Windows 11 23H2 machines to Windows 11 24H2 — the content download failed initially. This issue was resolved with the May 2025 update. However, we continued to face multiple challenges while upgrading to 24H2 using the Feature Update method due to the large content size (~11 GB).
We raised a case with Microsoft, but no solution was provided. As a workaround, we have started upgrading the machines using the in-place upgrade method via Task Sequence.
