Hello @Bree,
I do NOT know if this will be of any use to you but this is part of a Script I wrote that might give you the Product Key. I do NOT know if it will work on Win 7 but it works on Win 10 & Win 11.
Copy & Paste the following ALL at once into Notepad and Save it [ Desktop ] as a .bat file and then run it.
Code:
@echo off
:: 10F_Bree
if not "%1"=="max" start /max cmd /c %0 max & Exit /b
:Product_Key_License
echo.
PowerShell Write-Host -ForegroundColor Red ^
