NOTE: 

  • Windows Product key is not required when you have a Microsoft account linked to your Windows product key.
  • If you are using Windows 10 and want to reinstall Windows 10 in the system, then there is no need for the Product Key. The system will automatically detect that this device is activated earlier and just needs to be re-activated.
  • The key is required when you are using an earlier version of Windows(versions earlier to Windows 10)and want to re-install Windows 10 in the system and Microsoft account is not linked to the product key.

Method 1: From Authenticity Sticker

NOTE: This method works for systems that came with Windows 7 or earlier versions.

The PCs come with a sticker called Certificate of Authenticity(COA) labeled on the bottom for the laptops and labeled on either backside or sides or top in the desktops. The Windows product key will be printed on the COA sticker.

If you see that the sticker has worn out or you cannot read the contents in the sticker as the contents have erased or smudged, then try the next method listed below.

Method 2: From UEFI firmware

NOTE: If the system uses Windows 8 and above, then the Product key will be embedded in UEFI firmware.

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

  1. The reason for the two different keys is that your system may not have come with windows 10 and the UEFI method 2 will pull the serial from the original OS of the system whereas the registry method 3 pulls the serial from your current OS

  2. Hello,
    Thank you but the last 2 methods yield two different keys. Can you help me understand why and which is the true key?
