Where is the 8 to 10 product key after a upgrade?

Then i can't predict the outcome on 10, i never (needed to) use(d) MAKs ever.

But like to know what the QT will report (don't post the key itself but i'd like to know if the QT reports the used key).

 

MAKs are generally not stored to the Registry.

Other keys can be removed with:

Code:

slmgr.vbs /cpky

 

If you perform a clean install of Win10 it should now activate with the generic default key. From the admin cmd prompt you can see some details of your current key with "slmgr /dli" or "slmgr /dlv"...

 

If you really want to know the key that is stored on your computer, use yamicsoft Windows 10 Manager => System Information, for example, but you can also find it in encrypted form in the registry.

Code:

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ => right panel => DigitalProductId

To see this for real, you can use the following .vbs script but remember, it is a generic key and cannot be used to activate Windows. However, all users of the same version will find the same key on their computer after the actual activation, if was activated electronically or after using any genuine Windows 7, 8, 8.1 key.

Spoiler: .vbs script

Code:

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

 

For me your situation a little confusing.
At first, you said you upgraded from Windows 8 to Windows 10 and said that Windows 10 was activated.
However, nowhere have you told me how Windows 8 was activated and what activation method was used there.
If you use MAK or KMS, my suggested .vbs and other methods won't show anything. They only work if your Windows 8 was OEM or Retail and now Windows 10 is activated with a digital license. That is, you will see the message "Windows is activated with a digital license linked to your Microsoft account".
(Settings => Update and Security => Activation)
So, how Your Windows 8 was activated and how Your current Windows 10 have been activated?

 

Yeah MAKs aren't shown in the QT, there should be some more info in the report, under the stuff you published, thanks for testing

Your system has a HWID based on the MAK.

MAK key is NEVER EVER stored on local machine in any form or shape

 

Well the Product Key program discovers not only the Windows activation code but also Internet Explorer (if it is installed of course) in this way the choice is yours naturally

 

If you have a legit MAK key,you should be able to visit the VLSC to get your key.
