Some of the worse hits for the search were the Microsoft documentation pages. They have a standard format which involves small print, over-complicated explanations for simple tasks, and lots of requests for feedback to ignore. I mostly read them to find search terms that will find the real answer.
The good news is - it is simple, but Microsoft probably doesn't want you to know that. The Windows 8 and 10 experience is based on using a Microsoft account to log on to the PC so all the settings can be synced across devices. Using a "local" account that is not a Microsoft account is strongly discouraged and barely explained. But for the vast majority of business users who log on using a domain account managed by corporate administrators, logging on to the Windows 8 PC with a Microsoft account is not an option.
