如何在贴纸损坏时查找 Windows 产品密钥

Question

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

我自己不是电源外壳用户，无法完全遵循脚本中的代码。

这将是一个有用的脚本，可帮助在升级操作系统时重新安装。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 = "SoftwareMicrosoftWindows NTCurrentVersion"
    $regValue = "DigitalProductId"
    Foreach ($target in $targets) {
        $productKey = $null
        $win32os = $null
        $wmi = [WMIClass]"\$targetrootdefault: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

我认为YouTube视频有点过头了，您可以简单地将其内容剪切并粘贴到PowerShell窗口中，而无需使用执行策略和导入文件。

只需打开PowerShell，将以下代码粘贴到其中，然后按几次Enter键，直到返回。

param ($targets = ".")
$hklm = 2147483650
$regPath = "SoftwareMicrosoftWindows NTCurrentVersion"
$regValue = "DigitalProductId4"
Foreach ($target in $targets) {
    $productKey = $null
    $win32os = $null
    $wmi = [WMIClass]"\$targetrootdefault: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
}

我强烈建议备份硬盘驱动器（或完全替换它），以防脚本未正确解密。通过所有这些发现它是错误的并且您刚刚擦除了以前的操作系统，这有点糟糕。

试图解释代码的作用。

脚本正在读取注册表值SoftwareMicrosoftWindows NTCurrentVersionDigitalProductId并提取相关部分

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

正如代码中的注释所说，然后它解码（"解密"）for循环中的值。注册表值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，代码显示产品密钥以及几个系统值

$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

---

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

$regValue = "DigitalProductId"

与

$regValue = "DigitalProductId4"

代码错误，您解密的密钥错误...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 = "SoftwareMicrosoftWindows NTCurrentVersion"
    $regValue = "DigitalProductId"
    Foreach ($target in $targets) {
        $productKey = $null
        $win32os = $null
        $wmi = [WMIClass]"\$targetrootdefault: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
