Find Your Windows 10 Product Key Using a Windows Registry Method

First, open Notepad by right-clicking anywhere on the desktop, hovering over “New,” and then selecting “Text Document” from the menu.

Copy and paste this code into Notepad:

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

Next, click the “File” tab and select “Save As.”

In File Explorer, set the “Save As Type” dropdown to “All Files” and give your file a name. You can use any name, but it has to be a .vbs file You can name it something like: productkey.vbs

Once you’ve entered a file name, save the file.
