Hello,

I was previously on Windows 7 and then I upgraded to Windows 10 for free in 2019, I believe (I can't remember why or how since I didn't perform the upgrade myself). I would like to format my PC, so I'm looking for my Windows 10 license key, but I can't find it anywhere.

If you could help me, I would be grateful.

Thank you in advance.

PS: with Windows+R/cmd/wmic path softwarelicensingservice get OA3xOriginalProductKey nothing shows up where the key should be displayed.

Configuration: Windows / Chrome 84.0.4147.105

    Hi

    You don't need it, your PC is now recognized by the activation servers

    At the time of reinstallation, you will click on "I don't have a product key" and the installation will proceed

    Windows will be automatically reactivated as soon as an Internet connection is established

    It has nothing to do with a Microsoft account, which may be useful for recovering the license in case of hardware changes

    Hello
    you have an electronic key installed by Microsoft that validates Win10 as an heir to the Win7 key

    an upgrade from 7 to 10 does not entitle you to a free license

    A thank you is appreciated.
    Mark as resolved if your problem has been solved. I use the informal "you" with everyone.

      Hello Redbart
      Either I didn't understand well, or the message is confusing.
      If he made an update in due time, the PC is registered with Microsoft and therefore reinstalling Windows 10 is not a problem because he doesn't need a "key".

      Hi

      Sorry but yes, all my W10 PCs come from this free migration.

    If the digital key is linked to a Microsoft account

    Windows 10 allows a reset:

      I didn't understand anything

      If you have a Windows 10 license issue, start your own thread by clearly explaining this.

    Hello,

    It is possible to retrieve your Windows license key using a very easy-to-set-up script. To begin, open Notepad and copy the following 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 255s
    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


    Then save the text document by going to File > Save As and name it by adding the .vbs extension (e.g., Windows License.vbs). In "Type," set it to All Files.

    Once saved, open the file. A dialog box will then appear with your Windows license key.

    Hello,
    No activation key is needed to upgrade to Windows 10.
    Normally with Windows 7, the activation key is located underneath the computer.

    Ps:
    sometimes you need to remove the battery to find it.

      No need to look for the key, he has already migrated from 7 to 10.
