Found valid list of superseded updates.
ERROR: File integrity verification failure.
I'm using WSUS Offline Update 11.5, and I erased my c:\wsus folder to make sure there wasn't something in it causing the problem.
Looks like you have a corrupt update with a changed hash in your repository.
1. Delete the affected update .\client\w100\glb\windows10.0-kb4103731-x86_8b30bb79080122f208f8df28306957d75d297ba3.cab to have it re-downloaded.
3. Do a new download run.
