How to get Windows 8 (8.1) Product Key without Software Step 1 In this step, user need to collect some script or code from the Microsoft Technet website. We also provided the script here, but keep an eye on Microsoft Technet website if it doesn’t work for you (they updates the code). Here is the script, function Get-WindowsKey { ## function to retrieve the Windows Product Key from any PC param ($targets = .) $hklm = 2147483650 $regPath = Software\Microsoft\Windows NT\CurrentVersion $regValue = DigitalProductId64 Foreach ($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 } } Copy the above code and open Notepad then paste the script exactly. Now save the file with name “RecoverKey.ps1“. Step 2 Here comes the second step.
