A rollback manager creates a restore point on a computer. The rollback manager stores a reboot indicator in non-revertible storage. The rollback manager monitors the reboot indicator to detect an unexpected reboot during deployment of a modification. The rollback manager configures the computer responsive to the reboot indicator. The rollback manager can roll back the system state, responsive to detecting a failed modification deployment. The rollback manager can deem the computer to be stable, responsive to detecting a successful modification deployment.
