Finding Windows Product Key

[Smell My Name]

So i lost my product key and i need it to reinstall windows on a pc build i built myself, I  used windows powershell with this script : 

(Get-WmiObject -query 'select * from SoftwareLicensingService').OA3xOriginalProductKey

and i also made a vbs file using this script:

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

 

 

 

When I use both scripts they show entirely different "product keys" and I don't know why.

With 10, the product key is either tied to the motherboard or your microsoft account, If you signed in.

 

I'd recommend tying it to your ms account just for ease of access. If you're reinstalling on the same machine though it should automatically verify the key through your motherboard

Agreed

 

@Smell My Name, if this is the same PC, with no new Hardware, all you need to do is reinstall Windows, and skip the "Enter a Product Key" part of the initial configuration. After you get to the desktop, it should activate automatically.

The reason I am doing this is because I and upgrading the mobo and processor, getting a Ryzen 7 processor.

In that case, there are specific steps Microsoft has put out to prepare the computer for the upgrade:

Because you upgraded from 7 to 10, you don't actually have a Product Key for Windows 10. Instead, you've got a "Digital License".

 

TL;DR, you need to associate your Windows 10 license with a Microsoft Account, then when you reinstall Windows, sign in with that account and run the activation troubleshooter. See my link for detailed steps.

Awesome I can use this actually since I should be able to use the Digital License instead of the original key right? I suppose there is no actual real way for me to get the old windows 7 key either as well correct?

Correct - upon a Windows 10 upgrade, the Windows 7 key is converted into the Digital License. The old 7 key can still be used, if you happen to know what it is, but that info isn't stored in Windows 10 AFAIK.

I actually used belarc and got it that way. Found out i actually used my windows 10 key on there... Thought I used a different one oops.
