x64-based Vista systems will require digitally signed drivers
Microsoft has announced
that any kernel-mode software running Windows Vista x64 must be digitally
signed. Besides the announcement, Microsoft also released a Word
document that covers the signing process for kernel-mode code in Vista.
For Vista, the digital signing of kernel-mode code means that:
- only administrators can install unsigned drivers
- drivers that stream protected content must be signed
- unsigned kernel-mode software will not run on x64-based systems
-anyone wishing to write drivers for Vista must have a Publisher Identity Certificate (PIC) from Microsoft.
