Ppl need a KMS key to activate, which is not leaked yet and worse, even if you have a KMS key, you WONT be available to activate cause the KMS (legit) servers are NOT upgrated. And this, 8.1 uses the protocol v6, which means that the "standalone" kms activator (like kmspico) it WONT work, because its a different protocol with a different key. So, RELAX, and wait like october, at least. :)
