Checking for the product key of a previous Windows setup could be useful. The link provided offers a tool to view keys from past installations.
There are a few things to extract your licence key. Not sure how it works with Windows 10/11, but normally, you can reinstall Windows as long as your motherboard didn't change. This command in the command prompt ; wmic path softwarelicensingservice get OA3xOriginalProductKey Also, not sure it will work, but there's a VBS script to extract your Windows key from the registry (EDIT : copy/paste in a text file, and rename it to .VBS) ; 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
Some details to keep in mind: wmic isn't available in Windows 11 for its upcoming release. It has been phased out over many years and is no longer supported. Be aware that WMI remains functional and is still available, not WMIC. The command you tried won't function. If you're using a Microsoft account and reinstalled without entering the product key, you'll only have a generic trial key, not the real one. Incorrect tool recommended. Use the Scanner utility: https://www.nirsoft.net/utils/product_key_scanner.html. For OEM-built systems from companies like Dell, Acer, HP, etc., the product key is stored in the UEFI chip. Initially, after connecting online, Windows will retrieve and verify it. Just select "I don't have one" when prompted for the product key and choose the correct Windows edition. BIOS-based systems (Windows 7 and earlier) should display a sticker with the product key. This key won't match the one on the system unless activated by the OEM. Unless updated, the sticker key won't activate newer versions of Windows. Phone or chat activation is necessary to proceed. After that, it will work.
