If you did the free upgrade to Windows 10 and have a digital entitlement you don't need the key. It will be a generic key anyway. Google the last 5 characters of the key and you'll likely see what I mean. With a digital entitlement you just click skip when asked for a key on a clean install. If 10 came pre installed by the OEM the key will be embedded in the BIOS and read automatically by the install media.
