Find Your Windows Product Key Without Any Software
One thing I have always found frustrating about buying a PC with windows re-installed (among many things) is you don’t always have easy access to the product code. Sometimes it is posted on a sticker, but often it is not. How To Geek shows how to get the product code using a simple script.
Just open Notepad and paste in this code. Save it as a
file and then run it (or download a pre-made one)
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
It works very nicely! Press Ctrl+C while the dialog is open to copy your code to the clipboard.
