Windows Vista与XP 驱动签名的不同之处

Vista之家（www.vista123.com）：Windows Vista与XP 驱动签名的不同之处

微软3月份发布了Vista作系统在驱动签名方面与XP的差别比较。

在Windows XP中，驱动被分为3个级别：

　　1. In-box drivers are given first preference.

　　2. Windows Hardware Quality Labs (WHQL) signed drivers next.

　　3. Unsigned drivers are given lowest preference.

而Vista则大大扩展为8个分级：

　　1. Microsoft signed WHQL Certified Drivers.

　　2. Microsoft signed in-box drivers (NT Build Lab Certified).

　　3. Microsoft signed Windows Sustained Engineering Certified drivers.

　　4. Drivers that have been signed using Authenticode (Enterprise CA).

　　5. Drivers that have been signed using Authenticode (Class 3 CA Certified).

　　6. Drivers that have been signed using Authenticode (MAKECERT.EXE Certified).

　　7. Microsoft signed WHQL Certified drivers for a down level Windows Operating system.

　　8. Unsigned Drivers.

　　当驱动被安装时，这些行为判断结果会记录在Windows Vista系统文件夹下的setupapi.dev.log日志文件中。
