Finding the Windows product key VBScript

If you planned to do a reinstall of Windows but you cannot find your Windows product key, you are in luck because the product key is stored in the Windows registry. Follow the following steps to restore the product key:

Step 1: Copy and paste the following into a Notepad window:

Set WshShell = CreateObject(“WScript.Shell”)
MsgBox ConvertToKey(WshShell.RegRead(“HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DigitalProductId”))

Function ConvertToKey(Key)
Const KeyOffset = 52
i = 28
Chars = “BCDFGHJKMPQRTVWXY2346789”
Do
Cur = 0
x = 14
Do
Cur = Cur * 256
Cur = Key(x + KeyOffset) + Cur
Key(x + KeyOffset) = (Cur \ 24) And 255
Cur = Cur Mod 24
x = x -1
Loop While x >= 0
i = i -1
KeyOutput = Mid(Chars, Cur + 1, 1) & KeyOutput
If (((29 – i) Mod 6) = 0) And (i <> -1) Then
i = i -1
KeyOutput = “-” & KeyOutput
End If
Loop While i >= 0
ConvertToKey = KeyOutput
End Function

Step 2: You will need to use File -> Save As, change the “Save as type” to “All Files” and then name the file as <FILENAME>.vbs where <FILENAME> denotes the name of the file to be saved.

Step 3: Once you have saved the file, you can just double-click on the saved file, and the popup window will show you your product key.
