Microsoft's absence of continual updates on NGSCB progress in 2005 had caused industry insiders to speculate that NGSCB had been cancelled. At the Microsoft Management Summit event, Steve Ballmer said that the company would build on the security foundation it had started with the NGSCB to create a new set of virtualization technologies for Windows, which were later Hyper-V. Reports during WinHEC 2005 indicated Microsoft scaled back its plans for NGSCB, so that it could to ship Windows Vista—which had already been beset by numerous delays and even a "development reset"—within a reasonable timeframe; instead of isolating components, NGSCB would offer "Secure Startup" ("BitLocker Drive Encryption") to encrypt disk volumes and validate both pre-boot firmware and operating system components. Microsoft intended to deliver other aspects of NGSCB later. Jim Allchin stated NGSCB would "marry hardware and software to gain better security", which was instrumental in the development of BitLocker.
