拉动OEM键激活

Question

我是微软的合作伙伴，负责Surface 3和4的贷款和播种过程。我们每天对数百台设备进行重新成像，并在数字授权方面遇到问题。我需要一种方法从设备中提取OEM密钥，并使用该键强制激活。我正试图通过powershell脚本来实现这一点：

$computer = gc env:computername

$key = (Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey | Out-String


$service = get-wmiObject -query “select * from SoftwareLicensingService” -computername $computer

$service.InstallProductKey($key)

$service.RefreshLicenseStatus()

我发现了一个错误：

Exception calling "InstallProductKey" : ""
At line:7 char:1
+ $service.InstallProductKey((Get-WmiObject -query ‘select * from Softw ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : WMIMethodException

如果有更简单的方法来完成我正在做的事情，任何帮助都会被感激，或者修复这个错误。谢谢!

编辑:添加异常陷阱，新错误

尝试将.Trim()添加到$key的末尾

下面的代码也有类似的问题，它抛出了调用"InstallProductKey" : ""的相同错误异常--结果是$key返回了键字符串+几个空格。归功于@elexis捡起它。在任何地方都找不到解决办法。

$computer = gc env:computername
$key = (wmic path softwarelicensingservice get oa3xoriginalproductkey)[2].Trim() #<--The Trim is to remove the white space aftewards which causes an error
Write-Output $key

$service = get-wmiObject -query "select * from SoftwareLicensingService" -computername $computer
$service.InstallProductKey($key)
$service.RefreshLicenseStatus()
