Microsoft also announced details related to adoption and deployment of NGSCB at WinHEC 2003, stating that it would create a new value proposition for customers without significantly increasing the cost of computers; NGSCB adoption during the year of its introductory release was not anticipated and immediate support for servers was not expected. On the last day of the conference, Biddle said NGSCB needed to provide users with a way to differentiate between secured and unsecured windows—that a secure window should be "noticeably different" to help protect users from spoofing attacks; Nvidia was the earliest to announce this feature. WinHEC 2003 represented an important development milestone for NGSCB. Microsoft dedicated several hours to presentations and released many technical whitepapers, and companies including Atmel, Comodo Group, Fujitsu, and SafeNet produced preliminary hardware for the demonstration. Microsoft also demonstrated NGSCB at several U.S. campuses in California and in New York in June 2003.
