1. A method for determining whether an activation process key which is used for activation of an operating system (OS) product is successfully injected into an information handling system, the method comprising: initiating a key injection procedure to inject into an information handling system at least one activation process key to support one of an automated system activation and a manual system activation; in response to completion of the initiated key injection procedure, storing a copy of a selected character sequence of each activation process key utilized in the key injection procedure; and initiating an injection verification to determine whether the key injection procedure completed successfully, said initiating said injection verification comprising securely performing the injection verification to determine whether the key injection procedure successfully injected an activation process key into the information handling system by utilizing the selected character sequence of the activation process key and without fully identifying the activation process key, and said initiating the injection verification further comprising: comparing the stored copy of a selected character sequence for a unique digital product key (DPK) to a character sequence reported by an OS image on a selected information handling system on which key injection to support automated system activation was performed; and in response to the stored copy of the selected character sequence for the unique DPK matching the reported character sequence, identifying the selected information handling system as a “passing” system on which the key injection procedure was successfully performed.
