1.Open Notepad.
2.Copy and paste the following text into the notepad window
function Get-WindowsKey {
## function to retrieve the Windows Product Key from any PC
## by Jakob Bindslet ([email protected])
param ($targets = ".")
$hklm = 2147483650
$regPath = "Software\Microsoft\Windows NT\CurrentVersion"
$regValue = "DigitalProductId"
Foreach ($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
}
}

3. Save the text above into a file with the ".ps1" extension on the Desktop.

Bonus tip: To make sure that you saving the file with the ".ps1" extension, you can type its name with double quotes, for example, "GetProductKey.ps1".

4. Open the Powershell console as administrator by typing "powershell" in the search box of the Start Menu or right on the Start Screen and then press CTRL+SHIFT+Enter. This will open the elevated Powershell window.
5. Enable the execution of local files which are not digitally signed. This can be done with the following command:
Set-ExecutionPolicy RemoteSigned
Press Enter to allow the execution policy to be changed.

6. Now you should type the following command:
Import-Module C:\Users\Winaero\Desktop\GetProductKey.ps1; Get-WindowsKey
7. Voila, you product key is displayed on the screen!

Thanks for sharing! For me Keyfinder is a better option instead going into such lengthy process to get the Windows key information, Its a portable build, no installation, easy to use.

By the way you let us go far away, make sure the next time to explain in detail your problem, the solution was in the first post of a friend, and you go to this hard one to recover your key lol! and its a Daz key !

The key that appears is just the same key i can find in any recovery tool, you can't recover the key before the one you did instal by using windows loader, which means you just try to get it in a different way.

I say you can't recover the old key if you use windows loader it means you will get a modified key not the one that MS install in the first time in your computer

As it's a work pc at home , i would imagine it's a laptop and will have a factory reset available ( just remember to save files first)

@gee, the pc will be in exactly the same state as when the company purchased it using factory reset.

Edit just seen your post above.

Daz has made the OS genuine ( if that is what you used, no worries)

If microsoft finds out they will contact the fbi about it. Then within a few hours the swat team will be knocking at your door...
