如何获取已安装设备的驱动程序密钥？

Question

不幸的是，这个问题是在 4 年前提出的，但目前还没有答案如何以编程方式获取驱动程序的驱动程序密钥？

其实如果有答案我就不会再问了。

我有一个依赖Naps2扫描仪软件的软件。我想生成profiles.xml文件，它取决于Driver Key和DeviceName

profiles.xml 如下所示：

搜索 Windows 设备后，我发现驱动程序密钥 {6BDD1FC6-810F-11D0-BEC7-08002BE2092F} 在这里：

我需要的是一个 PowerShell 脚本或单行脚本，为我提供一个驱动程序密钥，例如 "{6BDD1FC6-810F-11D0-BEC7-08002BE2092F} "，其中包含零或任何数字，具体取决于连接到计算机的扫描仪数量（仅限类 GUID {6BDD1FC6-810F-11D0-BEC7-08002BE2092F}），设备名称如下：

Get-WmiObject Win32_PNPEntity | Where-Object { $_.PNPCLass -eq "Image"} | select *

或者

Get-WmiObject Win32_PnPSignedDriver | Where-Object { $_.PNPCLass -eq "Image" } | select *

注意事项：并非所有已知的 cmdlet 在所有 PS 版本/操作系统平台上都可用。

我使用自定义函数根据需要动态获取此类信息。

Answer 2

我猜你想要的是班级 GUID。您还标记了 Posh 2/3/4.0，但是，使用

Get-CIMInstance

是正确的方法：在 Powershell 3.0 中引入 - Get-CIMInstance - 为您提供与 Get-WMIObject 相同的功能，而无需担心太多安全问题。

Get-CimInstance -Namespace root/cimv2 -ClassName Win32_PNPEntity | Where-Object PNPClass -EQ "Image" | Select-Object -ExpandProperty ClassGuid

此外，尝试包含

-Namespace

参数。即使

Get-CIMInstance

cmdlet 指向命名空间的根，它也往往会更快地查询对象；一定是在幕后做某事。

Answer 3

我刚刚回答了您提到的原始问题，但为了完整起见，我再次回答了。我最初是为网络适配器编写的，但我认为它可以轻松适应（没有双关语）任何其他设备，包括扫描仪。我花了很多时间进行研究，所以我希望其他人可能会发现这很有用。

$devObjs = Get-WmiObject -Class win32_pnpEntity -Filter 'Name like "Brother%"'
foreach ($dev in $devObjs)
{
$guid = $dev.GetDeviceProperties().DeviceProperties | where KeyName -eq 'DEVPKEY_Device_Driver' | select -ExpandProperty 'Data'
Write-Host $guid
}

或者只是...

foreach ($dev in Get-WmiObject -Class win32_pnpEntity -Filter 'Name like "Brother%"')
{
$guid = $dev.GetDeviceProperties().DeviceProperties | where KeyName -eq 'DEVPKEY_Device_Driver' | select -ExpandProperty 'Data'
Write-Host $guid
}
