Re: It's an improvement
Yes to get past the need for using a Outlook account you simply click the "Create new account" and then you see an option to login using a plain local account.
A little counter intuitive but going forward the more logins they get the better for them I guess. Plus it helps when customers moan they can't get into the Apps store.
I have tried 8/10 with a MS login and its pretty neat as soon as I logged into my first 10 VM it automatically looked like my Windows 8.1 machine even down to the desktop theme.
