[Correction: This system does not possess that function. An original Ultron program was stored in a data storage device. According to records, when an organization called the "Wrecking Crew" attacked Avengers Tower, the data entered the Avengers system through a data scan and reconstructed the system's data by reviewing records of Ultron activity.]
