Now a real OEM key needs to leak before I can released an updated loader. Thanks for the SLIC though @ frwil.
You don't find one, you create one - get the Keyinfo app (see the sticky product key decoding thread in the Windows 8 forums) and use 9e2 as the group ID. the keyid and secret can be any random number, although using 0 for the keyid is arguably a good idea since that's what is in the official MS KMS key, although either way, it's not really of consequence.
I guess you can't read, I have no futher information to give; if you can't figure it out from what I've said, you're never going to.
