    How do I find my Product Key?


    I activated Windows 8 via phone. I gave them the 9 groups of digits and activated successfully. How do I find out my product key? I'm trying to "Add features to Windows 8"

    The numbers that you gave Microsoft to activate Win8 was a product ID number, generated by Windows after a license key was entered.

    The 25 character license key is included with the confirmation email, if you bought Win8 by download. If you have a retail package, it's on the COA (certificate of authenticity).

    Make sure that you keep a safe copy of that code. It contains the whole value of the Windows license.

    Magic Jellybean Keyfinder still works well with windows 8.

    Interesting, the key shown by Magic Jellybean Keyfinder does not match the key I was given by Microsoft, which is also the key I entered during the install. I guess that is no longer a valid way to find a product key.

    Your product key is in the email Windows Store sent you.

    Theog, you seem to know the ins and out of this stuff so I'll ask you a question.
    Activating by phone doesn't actually change your product code does it?
    So in the OP's case, the product code is the one he or she entered originally right?

    Now if that's true, I have a question for the OP. Did you not write down or record the product code you used during the install?
    Also, why do you need it to add features? It can't be used to add any features, you need a new special code for that.

    By activating the product code, code is replaced with a non-usable code.

    Some older keyfinder use the old decryption method which don't fit to Windows 8.

    Copy the following to a text file and rename the text file to *.vbs. With double click on this vbs file the correct product key is shown:
    Code:
    Set WshShell = CreateObject("WScript.Shell")
    Key = "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\"
    DigitalID = WshShell.RegRead(key & "DigitalProductId")
    
    ProductName = "Product Name: " & WshShell.RegRead(Key & "ProductName") & vbNewLine
    ProductID = "Product ID: " & WshShell.RegRead(Key & "ProductID") & vbNewLine
    ProductKey = "Installed Key: " & ConvertToKey(DigitalID)
    ProductID = ProductName & ProductID & ProductKey
    
    If vbYes = MsgBox(ProductId & vblf & vblf & "Save to a file?", vbYesNo + vbQuestion, "Windows Key Information") then
       Save ProductID
    End if
    
    Function ConvertToKey(Key)
        Const KeyOffset = 52
        isWin8 = (Key(66) \ 6) And 1
        Key(66) = (Key(66) And &HF7) Or ((isWin8 And 2) * 4)
        i = 24
        Chars = "BCDFGHJKMPQRTVWXY2346789"
        Do
            Cur = 0
            X = 14
            Do
                Cur = Cur * 256
                Cur = Key(X + KeyOffset) + Cur
                Key(X + KeyOffset) = (Cur \ 24)
                Cur = Cur Mod 24
                X = X -1
            Loop While X >= 0
            i = i -1
            KeyOutput = Mid(Chars, Cur + 1, 1) & KeyOutput
            Last = Cur
        Loop While i >= 0
        If (isWin8 = 1) Then
            keypart1 = Mid(KeyOutput, 2, Last)
            insert = "N"
            KeyOutput = Replace(KeyOutput, keypart1, keypart1 & insert, 2, 1, 0)
            If Last = 0 Then KeyOutput = insert & KeyOutput
        End If
        a = Mid(KeyOutput, 1, 5)
        b = Mid(KeyOutput, 6, 5)
        c = Mid(KeyOutput, 11, 5)
        d = Mid(KeyOutput, 16, 5)
        e = Mid(KeyOutput, 21, 5)
        ConvertToKey = a & "-" & b & "-" & c & "-" & d & "-" & e
    End Function
    
    Function Save(Data)
        Const ForWRITING = 2
        Const asASCII = 0
        Dim fso, f, fName, ts
        fName = "Windows Key.txt"
        Set fso = CreateObject("Scripting.FileSystemObject")
        fso.CreateTextFile fName
        Set f = fso.GetFile(fName)
        Set f = f.OpenAsTextStream(ForWRITING, asASCII)
        f.Writeline Data
        f.Close
    End Function

    Not with retail keys, but only with MAK and KMS keys.
