PowerShell读取Windows产品密钥

之前大多数人可能用过VBS读取Windows产品密钥的VBS脚本，VBS脚本通常都比较隐晦、难懂，今天忙里偷闲，随手写了一个用于读取Windows产品密钥的PowerShell脚本。

代码如下：

          =====文件名：Get-WindowsProductKey.ps1=====  function Get-WindowsProductKey([string]$computer)  {  $comments =@'  author:fuhj(powershell#live.cn ,http://fuhaijun.com)  example: Get-WindowsProductKey .  '@  $reg = [WMIClass] ("\\" + $computer + "\root\default:StdRegProv")  $values = ]($reg.getbinaryvalue(2147483650,"SOFTWARE\Microsoft\Windows NT\CurrentVersion","DigitalProductId").uvalue)  $lookup = [char[]]("B","C","D","F","G","H","J","K","M","P","Q","R","T","V","W","X","Y","2","3","4","6","7","8","9")  $keyStartIndex = [int]52;  $keyEndIndex = [int]($keyStartIndex + 15);  $decodeLength = [int]29  $decodeStringLength = [int]15  $decodedChars = new-object char[] $decodeLength  $hexPid = new-object System.Collections.ArrayList  for ($i = $keyStartIndex; $i -le $keyEndIndex; $i++){ [void]$hexPid.Add($values[$i]) }  for ( $i = $decodeLength - 1; $i -ge 0; $i--)      {       if (($i + 1) % 6 -eq 0){$decodedChars[$i] = '-'}       else         {          $digitMapIndex = [int]0          for ($j = $decodeStringLength - 1; $j -ge 0; $j--)          {              $byteValue = [int](($digitMapIndex * [int]256) -bor $hexPid[$j]);              $hexPid[$j] =  ([math]::Floor($byteValue / 24));              $digitMapIndex = $byteValue % 24;              $decodedChars[$i] = $lookup[$digitMapIndex];           }          }       }  $STR = ''  $decodedChars | % { $str+=$_}  $STR  }  Get-WindowsProductKey .  

执行效果如下：
