* refactor: simplify Win11 Creator ISO workflow Keep no-driver ISO generation on the fast copy-only path. Inject exported drivers with one selected-index WIM mount, one Add-Driver pass, and one commit. Limit WinPE staging to boot-storage drivers and improve workflow validation coverage. * refactor: stage Win11 setup script fallback Copy the prepared setup script payloads into sources/$//Setup/Scripts so setup media does not depend solely on answer-file extension extraction. Keep the existing autounattend execution path unchanged and cover the fallback files in the Win11 Creator tests. * refactor: address codex feedback * refactor: run ISO verification in runspace Rename the ISO logger to Write-WinUtilISOLog so the shared runspace pool imports it automatically. Run Mount & Verify off the WPF thread with dispatcher-safe UI updates, and add Pester coverage for the runspace and logger contract. * refactor: address ISO review feedback Keep the selected ISO stable during background verification. Apply ContentDeliveryManager settings to both the first account and the default profile. Block FAT32 USB creation when install.esd exceeds the supported file size. * refactor: address ISO setup edge cases Set BypassNRO before OOBE so local account setup is available during Windows Setup. Detect registered DISM mounts during driver-injection cleanup so partial mount failures are discarded. * refactor: address ISO review edge cases Use the actual FAT32 file limit for install.esd USB checks. Disable ISO modification while mount verification is running. Apply unsupported-hardware notice suppression to the first user profile. * refactor: stage ISO setup safeguards earlier Set device encryption and reserved-storage registry guards before OOBE. Enable the OEM configuration-set fallback when setup scripts are staged there. * Update functions/private/Invoke-WinUtilISOUSB.ps1 Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> --------- Co-authored-by: Chris Titus <contact@christitus.com> Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com>
