Now, if you are someone who forget his/her Windows 10 product key or lost it in a system recovery, then yes, you do need a recovery software and get that precious key back.

How to Recover Windows 10 Product Key

Here are a few ways that can help you to recover your lost Windows 10 product key.

1. Check your certificate of authenticity sticker

If you bought your PC from a Microsoft retail shop, then there are high chances that your product key is available on the certificate of authenticity sticker that is usually found in the box of your PC or at the back side of your computer. The COA is basically a proof that your computer has a genuine copy of Windows installed in it. You just have to check the box in which you brought your PC. Mostly, the key is found on the back side of desktops and if you have a laptop, then there are chances of the COA sticker to be on the bottom side.

2. Check your PC's UEFI Firmware

If you bought a new PC with Windows 10 in it, then there are chances that your product key won't be on a sticker. Now, it is that time when manufacturers are getting more into technology, and instead of putting the key on the sticker, some manufacturers embed it in the system's UEFI firmware. Unlike the sticker, the key embedded in the UEFI firmware cannot be stolen, scratched or smudged off. It is extremely easy to check the UEFI firmware of your PC for the key. All you have to do is to open PowerShell on your PC and then Run the program with the administrative permission.

After that you need to type the following command in the PowerShell:
(Get-WmiObject -query 'select * from SoftwareLicensingService').OA3xOriginalProductKey


If your key is actually embedded in the UEFI then after following the above process, you will have your key right in front of you on the screen.

3. Check the Windows Registry

If both of the above-mentioned methods won't work then don't worry and try checking Windows Registry instead, especially if you haven't formatted your computer.


For this you have to open your Notepad Window and then copy the following text in it:
Set WshShell = CreateObject("WScript.Shell")
MsgBox ConvertToKey(WshShell.RegRead("HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DigitalProductId"))

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

After entering it all in the notepad, you then have to save this file on your desktop as productkey.vbs. It will be saved as a Windows Scripting Host File. After that close notepad and then open the file again, you will then have the product key right in front of you.
