New for Getting Started with Windows Drivers
Windows Vista has new features and code-signing policies that affect the installation and operation of user-mode and kernel-mode software. These policies might affect the custom software components that development teams employ in their internal development environments. A development team must comply with the signing requirements of the Windows features that they use for their custom development environment. For more information see Signing a Driver, Driver Signing, and Signing Drivers for Public Release (Windows Vista and Later).
