How to Get Your Windows Product Key

It’s harder than I thought to get your current installation’s of Windows 7, 8, or 10’s product key. There’s no easy way to find it except for this nice script.

1) Open Notepad

Search for the Notepad program that comes with every installation of Windows. When you open Notepad, an Untitled instance of Notepad should open.

2) Copy and paste the following script into Notepad:

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"
    Do
       	Current= 0
        j = 14
        Do
           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)
