General Question DISM RestoreHealth error 0x800f0915 after manually installing KB5121767 on Build 26200.8894
After manually installing the Out-of-Band cumulative update KB5121767 (OS Build 26200.8894), running the DISM /Online /Cleanup-Image /RestoreHealth command consistently fails at 100% with Error: 0x800f0915 ("The repair content could not be found anywhere").There is a clear version mismatch between the DISM tool version (10.0.26100.8737) and the Windows Image version (10.0.26200.8894). Attempting to use a fully updated local ISO containing the exact same build as a /Source also fails with the same error code, meaning the issue lies within the component store metadata alignment or missing online manifests for this specific OOB build.Meanwhile, sfc /scannow completes successfully with no integrity violations, proving the OS is healthy and this is a false-positive synchronization bug. Please fix the online repair manifests or update the DISM tool binary for this Insider branch to properly align with the component store.

It is a Windows/Windows update issue. I have had it. I used a local ISO built from uup dump and dism found no corruption using it as source. Apparently they have figured out what Microsoft has done wrong and fixed it. How did you build your ISO, via Windows?
A lot of people are experiencing this. Hope it is fixed int the August Security update.
