Scott Hanselman had a guide on how to actually create an offline account in Win 8 (see: [1]).
It involves navigating to a "Create a Microsoft Account" screen, and then clicking the well-hidden "Sign in without a Microsoft Account" at the bottom. Quite a well thought out dark pattern, confused me at the time.
OK, I stand corrected. I recall that I had to use a Live account for a preview version of Windows 8 I installed on a test machine. Maybe my memory is off, I hadn't used it in ages.
