Else, you can use a **vbs** script, save the following commands into a file called for example get_windows_key.vbs:

<fs 75%>
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\\
</fs>

Now just double click on the file to get your key.
