IIRC you don't need bad credentials. It just offers to create a local account, without even asking to connect to the domain.
But yeah, I'm pretty sure the domain join is only an option on the pro and enterprise editions.
I've also found out that the domain join is only offered if it can contact the internet. I installed this on a brand-new laptop the other day, and it didn't detect the wifi card and it had no wired network. It absolutely refused to go past the "let me connect to the internet" phase until I went through the "hidden terminal" dance.
The "domain join" is misleading. It does not really join the domain, it just creates local account. Joining domain has to be done manually after installation. (Otherwise, network connection is a logical requirement for for domain join, you need to contact DC after all.)
This is in a stark contrast with current linux desktop distributions, which do allow domain join straight from their OOBE.
