WU_E_SETUP_DEFERRABLE_REBOOT_PENDING
WU_E_SETUP_DEFERRABLE_REBOOT_PENDING is a success-with-restart condition: the Windows Update Agent update succeeded, but restart is required to complete setup. The reboot may be deferred to a suitable maintenance window.
What to do
- Schedule a restart before relying on the updated agent for follow-up operations.
- Record the result as pending completion rather than as a failed agent update.
- After restart, verify that the original update workflow proceeds normally.
Record this as pending completion, not a failed setup
The code explicitly says Windows Update Agent was successfully updated and a reboot is required to complete setup. Automation should distinguish it from WU_E_SETUP_REBOOTREQUIRED and from handler execution failure. Preserve the result and schedule the restart according to the maintenance policy rather than repeatedly launching WUA setup.
After reboot, create a new update session and verify that search can proceed with the updated agent. If the same setup status returns, inspect the new Windows Update event sequence to determine whether the restart actually completed the setup phase. Reporting the pre-reboot HRESULT forever from a cached deployment record can make a successful maintenance cycle look like a persistent error.
