<P>    今天，微软发布了Vista在驱动签名方面与XP的差别比较。XP中，驱动被分为3个级别：</P>

<P>　　1. In-box drivers are given first preference.</P>

<P>　　2. Windows Hardware Quality Labs (WHQL) signed drivers next.</P>

<P>　　3. Unsigned drivers are given lowest preference.</P>

<P>　　而Vista则大大扩展为8个分级：</P>

<P>　　1. Microsoft signed WHQL Certified Drivers.</P>

<P>　　2. Microsoft signed in-box drivers (NT Build Lab Certified).</P>

<P>　　3. Microsoft signed Windows Sustained Engineering Certified drivers.</P>

<P>　　4. Drivers that have been signed using Authenticode (Enterprise CA).</P>

<P>　　5. Drivers that have been signed using Authenticode (Class 3 CA Certified).</P>

<P>　　6. Drivers that have been signed using Authenticode (MAKECERT.EXE Certified).</P>

<P>　　7. Microsoft signed WHQL Certified drivers for a down level Windows Operating system.</P>

<P>　　8. Unsigned Drivers.</P>

<P>　　当驱动被安装时，这些行为判断结果会记录在setupapi.dev.log日志文件中。</P>
