The University of Tsukuba uses KMS (Key Management Service) license authentication method.
\nIt does not require users to enter a product key when installing. Instead, it requires a periodic license authentication granted by the license authentication servers (KMS Host) in the university.
\nIn order to prevent unauthorized license authentication, information such as the time of license activation, PC IP address, PC name, and terminal unique ID is recorded.
