What this means for Windows Vista. To increase the safety and stability of the Microsoft Windows platform, beginning with Windows Vista:
•Users who are not administrators cannot install unsigned device drivers.
•Drivers must be signed for devices that stream protected content. This includes audio drivers that use Protected User Mode Audio (PUMA) and Protected Audio Path (PAP), and video device drivers that handle protected video path-output protection management (PVP-OPM) commands.
•Unsigned kernel-mode software will not load and will not run on x64-based systems.
Note: Even users with administrator privileges cannot load unsigned kernel-mode code on x64-based systems. This applies for any software module that loads in kernel mode, including device drivers, filter drivers, and kernel services.
•To optimize the performance of driver verification at boot time, boot-driver binaries must have an embedded Publisher Identity Certificate (PIC) in addition to the signed .cat file for the package.
Questi sono dei pazzi scatenati.... speriamo che trovino il modo di bypassare tutti questi pali che M$ sta mettendo, altrimenti mi sa che questo SO non lo installerò MAI... è una violazione della libertà.... se io volessi compliarmi dei drivers? non posso utilizzarli se non hanno la firma digitale?? ma che vadino a quel paese....
