It doesn't stop to talk, I should activate the product key when the product key already is active

[Eduardo_Bernal]

I must format my windows because my GPU had problems, so when it was resolved, the windows begin to accuse that I don't have an active product key, but when I access the configurations, the product key is active, how I did the windows stop to accuse me without sense?

I search to resolve this problem, but always I inserted one key, one error happened, same I try to insert the new key on the terminal, so I activated one server, which resolve my problem, check this tutorial to resolve the activation problems:

Obs: I recommend you active only the server if you have an active Windows and the Windows accuse you don't have a product key

In case you're just to find out your product key, same it is bugged, you need to copy and paste these commands on the notepad and save it likes VBS file, and execute the VBS file (I see this tutorial on the cool YouTube channel, but unfortunately this channel doesn't post videos in English):

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

Case the product key doesn't work or functioned for some bug; you can try to uninstall the product key using these commands:

slmgr.vbs /upk
slmgr.vbs /ipk
slmgr.vbs /ato

And as you insert again the product key, you need to come back to do the steps in this tutorial again, and you probably will know your product key:

If these steps don't function, you can format your windows or update your windows using the ISO file, whatever I think, it allows you did a clean installation, this installation or upgrade need to order a product key that you should annotate
