A few months ago, I had a non-feature update to my laptop running Windows 10 Pro (OEM) kick me to an OOBE-looking "finish setting up your computer" screen where the only way I was able to move forward and log on was to add an online account. Believe me, I spent an hour trying various things, and googling like a madman but I didn't manage to get around it. So I did it with a temporary email address. Then I removed the account. Still on Windows 10. Now and then I do a web search to see if other people ahve had this happening to them, but I've not been able to find anything. Then again, <insert the "search engines are crap" today discussion here>.
