Windows回滚设备驱动程序位置信息 [英] Windows rollback device driver location information

问题描述

当我们在Windows操作系统中为设备驱动程序选择回滚选项时，通常系统会将您带回到上次安装的驱动程序，但如果说我安装了3 4个驱动程序，那么它如何进入最后一个？即它必须存储有关系统文件中某处的最后一个驱动程序的一些信息。我试图找出它到底在哪里，谁都知道？

i试图搜索但没有找到任何相关信息，

When we select the rollback option for device driver in windows operating system, generally system takes you back to last installed driver, but if say i have 3 4 drivers installed then how does it go to last one? i.e. it must be storing some information about the last driver somewhere in system files. i was trying to find out where is it exactly , anyone knows?
i tried to search but did not find any relevant info,

推荐答案

Windows维护驱动程序存储区中的所有驱动程序。每次卸载活动驱动程序时，PnP驱动程序都会通过驱动程序存储区找到给定设备的驱动程序列表。 https：// msdn中描述了一个选举过程。 microsoft.com/en-us/library/windows/hardware/ff546225(v=vs.85).aspx [ ^ ]将选择适用于该设备的最佳驱动程序并安装它。您可以在setupapi日志中看到选举日志。



如果您想使用setup API手动枚举这些驱动程序，请查看https://msdn.microsoft.com/en-us/library/windows/hardware/ff544849 （v = vs.85）.aspx [ ^ ]

Windows maintains all the drivers in the driver store. Each time an active driver is uninstalled, the PnP driver goes through the driver store and finds the list of the drivers for the given device. There is an election process describes in https://msdn.microsoft.com/en-us/library/windows/hardware/ff546225(v=vs.85).aspx[^] that will choose the best driver applicable for the device and it is installed. You can see the election logs in setupapi logs.

If you want to manually enumerate through these drivers using setup API, then look at https://msdn.microsoft.com/en-us/library/windows/hardware/ff544849(v=vs.85).aspx[^]
