Method 1: Without using any Software or Tool

Step 1: Copy the below VB code

Set WshShell = CreateObject("WScript.Shell")
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

Try it.

Method 3: Using Belarc Advisor

I think its the best option if any of the above methods fails. Download Belarc Advisor and install the tool on PC. While at the installation, it will ask the user to run the system audit report. Allocate some time to this tool that fetches all the profile information on the console.

  2. If you run the above script you will see it fails at line 14, char 28. Something missing, as asks for ‘)’. Thanks ever so if you can correct it.

  3. The key that I got using your method is different from the key I got using Third party software. Why so? Which is correct?
