Generally, it is tough enough to read the key from the registry (ofcourse not possible) without using any tool. So, let’s see few methods to that fetches or decodes the serial key of Windows 8 from registry.

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
Cur = 0
x = 14
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: Open the Notepad and save the code with the name “TechEmptyKey.vbs“.

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.
