本文提供了一种预安装ClassFilter驱动的方法，通过使用`pnputil-axxx.inf`来解决在x64 Windows系统中安装ClassFilter驱动时遇到的签名验证失败问题，并通过WDK示例展示了如何利用SetupDiAPI插入过滤驱动。

Class Filter driver can be installed by "right click"->Insall, this will call InstallDevice*** API directly. The problem is this way .cat is not imported to system, consequently, driver signature verification failure may cause the driver cannot work on Windows x64. (x64 Windows enforces driver signature to load the driver.)

solution:

1. preinstall the driver before install:

pnputil -a xxx.inf.

WDK has a sample Addfilter to demonstrate how to insert a filter driver into the driver stack of a device. The sample illustrates how to insert such a filter driver by using the SetupDi APIs
