WU_E_UH_NEW_SERVICING_STACK_REQUIRED
WU_E_UH_NEW_SERVICING_STACK_REQUIRED is one of the most actionable handler errors. It means the machine must have a newer Servicing Stack Update (SSU) before the target update can be downloaded or installed.
What to do
- Install the latest applicable SSU or current cumulative update for the Windows version in use.
- After the servicing stack is updated, rescan and retry the failed update.
- If the machine is far behind, bring it closer to current maintenance before troubleshooting individual update packages.
