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

Method 4: Check the Windows 10 Product Box and Other Related Documents

If you physically purchased the Windows 10 software, then chances are the product key is printed on the box that came with the operating system. Do a thorough examination of the box to ensure that there are no hidden product keys over there.

While you are at it, open the mail account you used to register on your Windows. Search for any emails you received from Microsoft. One of them could contain the product key for your Windows 10.

You can also try scouring through the documents you received with the product. This includes your bill, your warranty and other Windows-related documents. Microsoft is often very secretive about the product key and hides it with the documents used for purchase.

For older versions of Windows, the product key is often printed on a sticker placed beneath your PC. Flip your laptop around and go through all the stickers there, if there are any. Chances are one of them may contain your product key.

Additional Tips

1. Contact the OEM: PCs that come pre-installed Windows usually have an Original Equipment Manufacturer (OEM). If they have stored the records of your purchase, then that manufacturer may have your product key.

2. Take it to a certified service centre: Regardless of what your PC has gone through, there is a high chance that the hard disk that holds your product key is still safe. A certified service centre may be able to help you find the product key. Make sure you take it to a trusted centre as some stores may use your product key for their own benefits.

3. Contact Microsoft: If none of the other options works, then contacting Microsoft becomes your only option. If you have an authentic version of Windows, then Microsoft will have your details stored somewhere. Their customer care service might use your Microsoft account and help retrieve the product key.

Finding the product key on your device can be a challenging task for many users. The precious nature of the code has caused Microsoft to keep the code very secretive and not make it easily available to the user. However, with the steps mentioned above, you can find the guarded key and retrieve your Windows OS.
