Using a local account on Windows 11 has its benefits, as explained by Microsoft on accident.
Microsoft inadvertently highlighted the benefits of using a local account over a Microsoft account on Windows 11 in a recent support page update.
Using a local account allows for offline sign-in, is independent of cloud services, and limits settings, files, and applications to a single device, enhancing privacy.
Despite these benefits, Microsoft requires internet access or workarounds for the initial setup of Windows 11, making it challenging to use a local account from the start.
It's a junk article, likely written by AI in part or entirely. Paragraphs and paragraphs of nothing just to reference a support article they found, all the while subtly implying a Windows account is a really good thing to use and everyone should use it.
You’re not wrong or anything, but “on accident” is used commonly in American English, so the author isn’t wrong either. I think it might have come from an association with “on purpose”, as in “I didn’t do it on purpose, I did it on accident.”
Unfortunately (or fortunately, depending on how you look at it), the rules of language only matter if people actually stick to them. Language shifts over time no matter who kicks or screams about it.
