   function Get-WindowsKey {
       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]
           $charsArray = "B","C","D","F","G","H","J","K","M","P","Q","R","T","V","W","X","Y","2","3","4","6","7","8","9"
           For ($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
