Windows Server 2022 RDS 10 Device CAL は、10台のデバイスがリモートデスクトップ経由で接続するためのクライアントアクセスライセンス（CAL）パックです。ユーザー単位ではなくデバイス単位でライセンスされるため、複数のユーザーが共有する端末やシンクライアント環境に最適です。
ライセンスの必要性
リモートデスクトップサービス（RDS）CALは、ユーザーまたはデバイスがWindows Serverにリモートデスクトップ経由で接続し、フルデスクトップセッション、RemoteApp公開アプリケーション、またはVDI（仮想デスクトップインフラストラクチャ）を利用する場合に、標準のWindows Server CALに加えて必要です。RDS CALがない場合、リモートデスクトップ接続はサーバーごとに2つの同時管理セッションに制限されます。
この10パックは、Windows Server 2022専用のデバイスCALを提供し、旧バージョンとの下位互換性があります。RDS CALは標準のWindows Server CALに追加して必要であり、その代わりになるものではありません。接続する各ユーザーまたはデバイスには、Windows Server CALとRDS CALの両方が必要です。
