I'm trying to automate via PowerShell a number of time consuming tasks that I have to preform to make a new VM template, one of which is removing all of the NICs from the VM and cleaning up the Device Manager of non present devices.

After removing the NICs from the VM, I've tried using the following code snippets, which do the same thing, to clean up Device Manager.

wmic nic where "(servicename is null)" delete

 

gwmi win32_networkadapter | ?{$_.ServiceName -eq $null} | rwmi

In both cases I receive the error "Provider is not capable of the attempted operation". Reviewing the event logs for WMI-Activity didn't seem to help: ResultCode = 0x80041024; PossibleCause = Unknown.

Has anyone be able to do something similar that removes the non present devices or is able to find an issue with the above commands?

EDIT: I've tried using DevCon to remove the device, but it seems to only work with present devices. I'm now combing through the registry to see if there is a specific key or set of keys that if removed would remove the NIC from Device Manager.

这个问题困扰了我一段时间，我想出了更多的手动方法，但它有效，所以希望这对其他人有帮助：

1）首先确保您要清除的设备列表是正确的：

Get-PnpDevice -class net | ? Status -eq Unknown | Select FriendlyName,InstanceId

2) 如果您对即将使用 Kaibosh 的 Get-NetAdapters 列表感到满意，请运行以下命令：

$Devs = Get-PnpDevice -class net | ? Status -eq Unknown | Select FriendlyName,InstanceId

ForEach ($Dev in $Devs) {
    Write-Host "Removing $($Dev.FriendlyName)" -ForegroundColor Cyan
    $RemoveKey = "HKLM:\SYSTEM\CurrentControlSet\Enum\$($Dev.InstanceId)"
    Get-Item $RemoveKey | Select-Object -ExpandProperty Property | %{ Remove-ItemProperty -Path $RemoveKey -Name $_ -Verbose }
}
Write-Host "Done.  Please restart!" -ForegroundColor Green

注意：您在步骤 1 中的适配器列表必须仅包含您要清除的适配器。如果您有额外的内容，请相应地调整过滤器（？Status -eq XXX，例如：？FriendlyName -like "Broadcom*"）！

由于这个页面，我设法解决了类似的问题。我稍微改进了该脚本并通过我的仓库发布了它：removeGhosts.ps1

使用此版本，可以像这样删除所有隐藏的网络设备：

$ removeGhosts.ps1 -narrowbyclass Net

这将在删除之前要求确认每个设备，该-Force选项可以抑制此行为。如果没有任何选项，脚本将删除所有隐藏的设备，这听起来像是提问者也感兴趣的东西。

此注册表项包含注册表中机器的所有硬件设置：
HKEY_LOCAL_MACHINE\system\currentcontrolset\enum

首先通过 WMI 查询当前和启用的网络适配器并获取它们的 PNPDeviceId。该值将告诉您网络适配器位于哪个子项中。

接下来查询每个子项的注册表并找到所有适配器。解析完整的注册表项以减少到与 PNPDeviceId 值相同的长度；大致是 PCI\VEN_80AD&DEV_15A2&SUBSYS_062D1028&REV_02\2&11483669&0&C9。

比较这两个列表并找到任何孤立的注册表项。找到后，通过枚举系统帐户删除注册表项将从设备管理器中删除网络适配器。我使用了 PSExec。

这是一些执行我刚才解释的代码。

# Declare variables
[string]$regIds = "";
[string]$Orphans = "";
[array]$SubKeys = @();
[array]$RegKeys = @();

# Query the present and enabled Network Adapters for the PNPDeviceId value
[array]$PNPDeviceIds = (gwmi Win32_NetworkAdapter -Filter "NetEnabled = true").PNPDeviceId;
for ($i = 0; $i -lt $PNPDeviceIds.Count; $i++){
    if ($SubKeys -NotContains $($PNPDeviceIds[$i].Split('\')[0] + "\" + $PNPDeviceIds[$i].Split('\')[1])){
        $SubKeys += $($PNPDeviceIds[$i].Split('\')[0] + "\" + $PNPDeviceIds[$i].Split('\')[1]);
}}

# Query the registry for all of the adapters
foreach ($SubKey in $SubKeys){
    [array]$Keys = reg query "hklm\system\currentcontrolset\enum\$SubKey"
    $Keys = $Keys[1..$($Keys.Count -1)];
    $RegKeys += $Keys;
}
# Parse the Keys
for ($i = 0; $i -lt $RegKeys.Count; $i++){ $regIds += "," + $($RegKeys[$i].Split('\')[4..6] -join '\'); }
$regIds = $regIds.TrimStart(",");

# Compare the registry to the present devices
for ($i = 0; $i -lt $regIds.Split(',').Count; $i++){
    if ($PNPDeviceIds -NotContains $regIds.Split(',')[$i]){
        $Orphans += "," + $regIds.Split(',')[$i];
}}
if ($Orphans.Length -gt 0){ $Orphans = $Orphans.TrimStart(","); }

# Delete the non-present devices
foreach ($Orphan in $Orphans)
{
    psexec.exe -s powershell.exe "reg delete 'hklm\system\currentcontrolset\enum\$Orphan'"
}

previos 脚本中的一些更改。

    if ($SubKeys -NotContains $($PNPDeviceIds[$i].Split('\')[0] + "\" + $PNPDeviceIds[$i].Split('\')[1])) {
        $SubKeys += $($PNPDeviceIds[$i].Split('\')[0] + "\" + $PNPDeviceIds[$i].Split('\')[1])
    }
}
