Overview of the Windows key

A Windows key, also referred to as a Windows Product Key, is a 25-character license key typically used to activate or reactivate the Windows operating system on desktops and laptops.

It looks like this:

    • TXUD8-USE8EX-U7XTM-LULE9-ULNX8
    • Or like this: XXXXX-XXXXX-XXXXX-XXXXX-XXXX

Aside from Windows activation, you may also need to find your Windows product key when migrating or transferring your system to a new HDD/SSD.

How to Find Your Windows Product Key for Free

You can find the product key for your Windows operating system in three places:

    1. On your computer. 2. On the COA sticker of the software. 3. On the Microsoft Windows Support platform.

Note that if you still have the Microsoft-provided Windows OS COA sticker that came with your computer, you can simply look up and find your Windows key on it. For official instructions, refer to Microsoft's website for how to find your Windows key.

#10. Notepad - Free Tool

A slightly more complex but effective Windows key finder

Find product key on Windows 11 via Notepad

The last option you can try is running a Notepad command tool to find your Windows key. It's a bit complicated, but it works on all versions of Windows.

Download: No installation required.

Find the product key for these products:

    All Windows operating systems.

How to use:

Step 1: Right-click on the desktop and create a new Notepad file.

Step 2: Copy and save the following content into Notepad:

```vb 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 ``` This code is VBScript and is used to extract and convert a Windows product key from a specific registry key value. It first creates a `WScript.Shell` object to access the registry and then calls the `ConvertToKey` function to process the retrieved data. Within the `ConvertToKey` function, it performs a series of calculations to decode the key and inserts dashes at the appropriate positions to format it as a standard product key.

Step 3: Click File > Save As > and under "Save as type," select "All Files."

Step 4. Rename the Notepad file as "productkey.vbs".

Step 5: Double-click the productkey file, and it will automatically scan and display the Windows key it finds.
