How to retrieve Windows 10 Pro license key

Question

How do i find, and unregister an Windows 10 Pro license?

I am unable to find the email containing the Windows key ( can i find it in another way?).

I want to retrieve the key and unregister it so that i can use it on new installation or hardware change (HDD/SSD/motherboard change)

I only have a local account on my computer and i dont want to have my microsoft account as a userprofile / linked to a local account.

-Thanks

You can try using one of the key finder utilities found on internet. You can do slmgr /upk but this only remove a local product key, nothing is sent to microsoft activation servers in the way of unregistering.

Hello there,

You can recover the key because Windows stores it in the registry. Here is how:

1. Open a new Notepad window
2. Copy and paste the following text into the window

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

3. Click File > Save As and save the file to your desktop as productkey.vbs. It's important to include the .vbs extension because this is a Windows Scripting Host file.
4. Close Notepad and double-click the file. Wait a few seconds, and then you will be presented with a popup displaying your product key:

Hope this resolves your Query !!
