很多人拿到驱动包准备安装驱动时，往往先想到通过鼠标右键-安装这种方式来安装驱动。且不说能不能安装成功，要支持这种安装方式，对inf文件有一定的要求：inf文件中需要包含[DefaultInstall]这样的节，这个节是右键安装时的Inf入口点(MSDN的原话:"An INF file's DefaultInstall section is accessed if a user selects the "Install" menu item after right-clicking on the INF file name.")。很遗憾的是，很多驱动安装包提供的Inf文件中并没有提供这样的节，因此右键安装并不能达到预期的效果("Providing a DefaultInstall section is optional. If an INF file does not include a DefaultInstall section, selecting "Install" after right-clicking on the file name causes an error message to be displayed."摘自MSDN)。
于是，聪明的你会想：既然inf文件中没有这样的节，我自己往文件中插入这样的节不就能达到目的了吗？这种变通的思维当然是值得肯定的，但是，最终可能还是安装失败。不要质疑是不是自己哪写的不对，再继续修改inf文件前，请看下MSDN上这段话:
"Remarks
DefaultInstall sections must not be used for device installations. Use DefaultInstall sections only for the installation of class filter drivers, class co-installers,
file system filters, and kernel driver services that are not associated with a device node (devnode).
Note The INF file of a driver package must not contain an INF DefaultInstall section if the driver package is to be digitally signed. For more information about
signing driver packages, see Driver Signing."
这段话翻译过来是说:DefaultInstall这种方式不适合设备安装(我们安装驱动不就是为了设备安装吗？)，仅适用于安装类过滤驱动/类协安装器/文件系统过滤驱动/以及内核驱动服务(即legendDriver，比如WinIO.sys)这些不涉及到设备节点(devnode)的情况。说的再通俗一点:inf文件中包含[Manufacturer]这样的节(这个节包含了驱动匹配的设备ID)就不应该再有[DefaultInstall]这样的字眼。
--------------------------------------------------
后记:
上面的内容不是很全面，只能说win7下右键安装inf文件的确不能成功，但到win10以后右键安装发生了变化。事情起因是一个同事的安装程序在win10下可以工作，但同样的程序在win7下失效，设备在设备管理器中还带着YB。以下分别是win7和win10的setupapi.dev.log

直观感受就是win10的安装日志内容远比win7丰富，并且有很多copyfile的动作。这不免会联想到难不成inf文件工作了？带着这种怀疑，我仔细查看了win10的setupapi.dev.log。在~~0~~处，右键安装时调用了SetupCopyOEMInf函数。这个函数怎么感觉有点眼熟？winddk 7600下devcon add_dp命令的实现就是调用了这个函数。调用这个函数的结果就是将驱动包安装在DriverStore下:
再看setupapi.dev.log ~~3~~处，在调用SetupCopyOEMInf函数完成后，系统紧接着做了一次[Update Device Driver]操作-----这相当于在设备管理器里做了一次更新设备驱动的操作。这使得设备管理器中YB的设备在DriverStore中匹配相应的设备驱动，正因为win10的这些变化导致了同事的安装程序在win7下工作失败。
