Question

我在这里找到了问题的可能解决方案：http://youtu.be/71Vc9QiraQE

我自己不是一个强大的shell用户，并且不能完全遵循脚本中的代码。

在升级操作系统时，帮助重新安装将是一个有用的脚本。我的问题是我想在使用它之前更多地了解它，或者至少被告知它看起来无害。

这是脚本：

function Get-WindowsKey {
    ## function to retrieve the Windows Product Key from any PC
    param ($targets = ".")
    $hklm = 2147483650
    $regPath = "Software\Microsoft\Windows NT\CurrentVersion"
    $regValue = "DigitalProductId"
    Foreach ($target in $targets) {
        $productKey = $null
        $win32os = $null
        $wmi = [WMIClass]"\\$target\root\default:stdRegProv"
        $data = $wmi.GetBinaryValue($hklm,$regPath,$regValue)
        $binArray = ($data.uValue)[52..66]
        $charsArray = "B","C","D","E","F","G","H","J","K","M","P","Q","R","T","V","W","X","Y","2","3","4","5","6","7","8","9"
        ## decrypt base24 encoded binary data
        For ($i = 24; $i -ge 0; $i--) {
            $k = 0
            For ($j = 14; $j -ge 0; $j--) {
                $k = $k * 256 -bxor $binArray[$j]
                $binArray[$j] = [math]::truncate($k / 24)
                $k = $k % 24
            }
            $productKey = $charsArray[$k] + $productKey
            If (($i % 5 -eq 0) -and ($i -ne 0)) {
                $productKey = "-" + $productKey
            }
        }
        $win32os = Get-WmiObject Win32_OperatingSystem -computer $target
        $obj = New-Object Object
        $obj | Add-Member Noteproperty Computer -value $target
        $obj | Add-Member Noteproperty Caption -value $win32os.Caption
        $obj | Add-Member Noteproperty CSDVersion -value $win32os.CSDVersion
        $obj | Add-Member Noteproperty OSArch -value $win32os.OSArchitecture
        $obj | Add-Member Noteproperty BuildNumber -value $win32os.BuildNumber
        $obj | Add-Member Noteproperty RegisteredTo -value $win32os.RegisteredUser
        $obj | Add-Member Noteproperty ProductID -value $win32os.SerialNumber
        $obj | Add-Member Noteproperty ProductKey -value $productkey
        $obj
    }
}
Get-WindowsKey

Windows PowerShell中使用的第一个命令：

Set-ExecutionPolicy RemoteSigned

如果第一个脚本不起作用，请尝试以下操作： 我能够使用它获取我的密钥，但我必须修复脚本，将最后一行更改为：

function Get-WindowsKey {
# ...
}
Get-WindowsKey localhost

Answer 1

我认为YouTube视频过度使用了一下，您只需将其中的内容剪切并粘贴到PowerShell窗口中，而无需使用executionpolicy并导入文件。

只需打开PowerShell，将下面的代码粘贴到其中，然后按Enter键几次，直到它返回。

param ($targets = ".")
$hklm = 2147483650
$regPath = "Software\Microsoft\Windows NT\CurrentVersion"
$regValue = "DigitalProductId4"
Foreach ($target in $targets) {
    $productKey = $null
    $win32os = $null
    $wmi = [WMIClass]"\\$target\root\default:stdRegProv"
    $data = $wmi.GetBinaryValue($hklm,$regPath,$regValue)
    $binArray = ($data.uValue)[52..66]
    $charsArray = "B","C","D","E","F","G","H","J","K","M","P","Q","R","T","V","W","X","Y","2","3","4","5","6","7","8","9"
    ## decrypt base24 encoded binary data to characters. 
    For ($i = 24; $i -ge 0; $i--) {
        $k = 0
        For ($j = 14; $j -ge 0; $j--) {
            $k = $k * 256 -bxor $binArray[$j]
            $binArray[$j] = [math]::truncate($k / 24)
            $k = $k % 24
        }
        $productKey = $charsArray[$k] + $productKey
        If (($i % 5 -eq 0) -and ($i -ne 0)) {
            $productKey = "-" + $productKey
        }
    }
    $win32os = Get-WmiObject Win32_OperatingSystem -computer $target
    $obj = New-Object Object
    $obj | Add-Member Noteproperty Computer -value $target
    $obj | Add-Member Noteproperty Caption -value $win32os.Caption
    $obj | Add-Member Noteproperty CSDVersion -value $win32os.CSDVersion
    $obj | Add-Member Noteproperty OSArch -value $win32os.OSArchitecture
    $obj | Add-Member Noteproperty BuildNumber -value $win32os.BuildNumber
    $obj | Add-Member Noteproperty RegisteredTo -value $win32os.RegisteredUser
    $obj | Add-Member Noteproperty ProductID -value $win32os.SerialNumber
    $obj | Add-Member Noteproperty ProductKey -value $productkey
    $obj
}

我强烈建议您备份硬盘驱动器（或完全更换硬盘驱动器），以防脚本无法正确解密。通过这一切来发现它的错误并且你刚刚抹掉了以前的操作系统会很糟糕。

尝试解释代码的作用。

脚本正在读取注册表值Software\Microsoft\Windows NT\CurrentVersion\DigitalProductId并提取相关部分

$wmi = [WMIClass]"\\$target\root\default:stdRegProv"
$data = $wmi.GetBinaryValue($hklm,$regPath,$regValue)
$binArray = ($data.uValue)[52..66]

正如代码中的注释所说，它然后解码（“解密”）for循环中的值。注册表值为base24编码。

$charsArray = "B","C","D","E","F","G","H","J","K","M","P","Q","R","T","V","W","X","Y","2","3","4","5","6","7","8","9"
For ($i = 24; $i -ge 0; $i--) {
    $k = 0
    For ($j = 14; $j -ge 0; $j--) {
        $k = $k * 256 -bxor $binArray[$j]
        $binArray[$j] = [math]::truncate($k / 24)
        $k = $k % 24
    }
    $productKey = $charsArray[$k] + $productKey
    If (($i % 5 -eq 0) -and ($i -ne 0)) {
        $productKey = "-" + $productKey
    }
}

最后，代码显示了产品密钥以及多个系统值

$win32os = Get-WmiObject Win32_OperatingSystem -computer $target
$obj = New-Object Object
$obj | Add-Member Noteproperty Computer -value $target
$obj | Add-Member Noteproperty Caption -value $win32os.Caption
$obj | Add-Member Noteproperty CSDVersion -value $win32os.CSDVersion
$obj | Add-Member Noteproperty OSArch -value $win32os.OSArchitecture
$obj | Add-Member Noteproperty BuildNumber -value $win32os.BuildNumber
$obj | Add-Member Noteproperty RegisteredTo -value $win32os.RegisteredUser
$obj | Add-Member Noteproperty ProductID -value $win32os.SerialNumber
$obj | Add-Member Noteproperty ProductKey -value $productkey
$obj

根据是零售版还是企业版，可以在DigitalProductId或DigitalProductId4中找到注册表值，例如

$regValue = "DigitalProductId"

VS

$regValue = "DigitalProductId4"

代码错误，您将密钥解密错误... 看看$ charsArray，没有E和其他几个...

function Get-WindowsKey {
    ## function to retrieve the Windows Product Key from any PC
    param ($targets = ".")
    $hklm = 2147483650
    $regPath = "Software\Microsoft\Windows NT\CurrentVersion"
    $regValue = "DigitalProductId"
    Foreach ($target in $targets) {
        $productKey = $null
        $win32os = $null
        $wmi = [WMIClass]"\\$target\root\default:stdRegProv"
        $data = $wmi.GetBinaryValue($hklm,$regPath,$regValue)
        $binArray = ($data.uValue)[52..66]
        $charsArray = "B","C","D","F","G","H","J","K","M","P","Q","R","T","V","W","X","Y","2","3","4","6","7","8","9"
        ## decrypt base24 encoded binary data
        For ($i = 24; $i -ge 0; $i--) {
            $k = 0
            For ($j = 14; $j -ge 0; $j--) {
                $k = $k * 256 -bxor $binArray[$j]
                $binArray[$j] = [math]::truncate($k / 24)
                $k = $k % 24
            }
            $productKey = $charsArray[$k] + $productKey
            If (($i % 5 -eq 0) -and ($i -ne 0)) {
                $productKey = "-" + $productKey
            }
        }
        $win32os = Get-WmiObject Win32_OperatingSystem -computer $target
        $obj = New-Object Object
        $obj | Add-Member Noteproperty Computer -value $target
        $obj | Add-Member Noteproperty Caption -value $win32os.Caption
        $obj | Add-Member Noteproperty CSDVersion -value $win32os.CSDVersion
        $obj | Add-Member Noteproperty OSArch -value $win32os.OSArchitecture
        $obj | Add-Member Noteproperty BuildNumber -value $win32os.BuildNumber
        $obj | Add-Member Noteproperty RegisteredTo -value $win32os.RegisteredUser
        $obj | Add-Member Noteproperty ProductID -value $win32os.SerialNumber
        $obj | Add-Member Noteproperty ProductKey -value $productkey
        $obj
    }
}
$key = Get-WindowsKey
$key.productkey
