I have a Dell Inspiron laptop with preinstalled Windows 8, upgraded to Windows 8.1 which cannot boot now. I am able to get in recovery screen with an USB installation kit.
In order to get the correct, legal Windows ISO I need to provide my product key. I understand that this is saved and connected to the BIOS/Mainboard/UEFI.
If I access the command prompt from the recovery menu, is there any command which provides me my OEM product key?
