           A Cost Analysis of Windows Vista Content Protection

                            Executive Summary

Windows Vista includes an extensive reworking of core OS elements in 
order to provide content protection for so-called "premium content", 
typically HD data from Blu-Ray and HD-DVD sources. Providing this 
protection incurs considerable costs in terms of system performance, 
system stability, technical support overhead, and hardware and 
software cost. These issues affect not only users of Vista but the 
entire PC industry, since the effects of the protection measures 
extend to cover all hardware and software that will ever come into 
contact with Vista, even if it's not used directly with Vista (for 
example hardware in a Macintosh computer or on a Linux server). This 
document analyses the cost involved in Vista's content protection, 
and the collateral damage that this incurs throughout the computer
