How to view your product key in Windows 10, Windows 8 and Windows 7

If you lost or forgot where you had stored your Windows product key, I have a solution for you. Today we will see how a simple VBS script can be used to show us the product key of an installed copy of Windows 10, Windows 8 or Windows 7. It is a simple solution to extract your product key from the OS installed on your PC without using any third party software. Here we go.

Actually, earlier I posted a similar solution which used PowerShell. but many users complained that it fails for them. PowerShell might require additional user skills and extra tweaks to run unsigned cmdlets.

Compared to PowerShell, this VBScript solution is almost perfect. All you need to do is to just click the file. To view your Windows 10 product key

  1. Open Notepad.
  2. Copy and paste the following text into the Notepad window
    Option Explicit 
    Dim objshell,path,DigitalID, Result 
    Set objshell = CreateObject("WScript.Shell")
    'Set registry key path
    Path = "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\"
    'Registry key value
    DigitalID = objshell.RegRead(Path & "DigitalProductId")
    Dim ProductName,ProductID,ProductKey,ProductData
    'Get ProductName, ProductID, ProductKey
    ProductName = "Product Name: " & objshell.RegRead(Path & "ProductName")
    ProductID = "Product ID: " & objshell.RegRead(Path & "ProductID")
    ProductKey = "Installed Key: " & ConvertToKey(DigitalID) 
    ProductData = ProductName  & vbNewLine & ProductID  & vbNewLine & ProductKey
    'Show messbox if save to a file 
    If vbYes = MsgBox(ProductData  & vblf & vblf & "Save to a file?", vbYesNo + vbQuestion, "BackUp Windows Key Information") then
       Save ProductData 
    End If
    'Convert binary to chars
    Function ConvertToKey(Key)
        Const KeyOffset = 52
        Dim isWin8, Maps, i, j, Current, KeyOutput, Last, keypart1, insert
        'Check if OS is Windows 8
        isWin8 = (Key(66) \ 6) And 1
        Key(66) = (Key(66) And &HF7) Or ((isWin8 And 2) * 4)
        i = 24
        Maps = "BCDFGHJKMPQRTVWXY2346789"
           	Current= 0
            j = 14
               Current = Current* 256
               Current = Key(j + KeyOffset) + Current
               Key(j + KeyOffset) = (Current \ 24)
               Current=Current Mod 24
                j = j -1
            Loop While j >= 0
            i = i -1
            KeyOutput = Mid(Maps,Current+ 1, 1) & KeyOutput
            Last = Current
        Loop While i >= 0 
        keypart1 = Mid(KeyOutput, 2, Last)
        insert = "N"
        KeyOutput = Replace(KeyOutput, keypart1, keypart1 & insert, 2, 1, 0)
        If Last = 0 Then KeyOutput = insert & KeyOutput
        ConvertToKey = Mid(KeyOutput, 1, 5) & "-" & Mid(KeyOutput, 6, 5) & "-" & Mid(KeyOutput, 11, 5) & "-" & Mid(KeyOutput, 16, 5) & "-" & Mid(KeyOutput, 21, 5)
    End Function
    'Save data to a file
    Function Save(Data)
        Dim fso, fName, txt,objshell,UserName
        Set objshell = CreateObject("")
        'Get current user name 
        UserName = objshell.ExpandEnvironmentStrings("%UserName%") 
        'Create a text file on desktop 
        fName = "C:\Users\" & UserName & "\Desktop\WindowsKeyInfo.txt"
        Set fso = CreateObject("Scripting.FileSystemObject")
        Set txt = fso.CreateTextFile(fName)
        txt.Writeline Data
    End Function
  3. Save the text above to a file with the “.vbs” extension on the Desktop.
    Bonus tip: To make sure that you saving the file correctly with the “.vbs” extension, you can type its name enclosed in double quotes, for example, “BackupWindowsKey.vbs”.

  4. Now open your BackupWindowsKey.vbs file
  5. Voila, you product key is displayed on the screen!
