Setting up a local account on Windows 10 was already a convoluted process: people had to make sure their device wasn't connected to the internet, confirm they don't have internet, click "Continue with limited setup" and then finally select the option to create an offline account. Otherwise the setup process would all but force them into setting up a Microsoft Account even though they really only wanted to use the system they had paid for. So how could that process be made even worse? The "Offline account" option has simply been renamed to "Domain join instead".
Once clicking this option, you will see the familiar prompt that allows you to set your username and go through the motions to complete your install. Microsoft of course still tries once again to get you to create an online account, but you obviously don't have to at this point. It's a small change, but one that is likely to leave more than a few customers scratching their heads on how to create a local account. And that is likely just what Microsoft wanted to do; sow confusion so that users would throw their hands up in frustration and simply cave to creating a Microsoft Account.
