MsgBox ConvertToKey(WshShell.RegRead('HKLMSOFTWAREMicrosoftWindows NTCurrentVersionDigitalProductId'))

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: Save the notepad as 'windowsproudctkey.vbs'.

1. Click File > Save As in Notepad.
