        $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
