The most appropriate method for upgrading the two computers quickly without retaining user settings is a clean installation. This method involves completely wiping the existing operating system and user data, then installing a fresh version of the operating system. Since the requirement is not to preserve user settings, a clean installation ensures that the new operating system is installed on a blank slate, eliminating any previous configuration or data.

This approach is particularly useful in scenarios where a technician wants to ensure that the systems are running optimally with the latest software and configurations. While unattended installation allows for a quick and automated setup process, it typically retains existing settings or personal files unless specifically configured otherwise. In-place upgrades, on the other hand, generally preserve user settings and data as they upgrade the existing operating system to a newer version. Therefore, for a rapid, no-retention upgrade, the clean installation method fits the requirements perfectly.
