Windows 10 keeps telling me that an account connected to my PC's local login account needs to be "fixed", but the problem account no longer exists. I cannot "disconnect" it because Windows 10 tells me it does not belong to a domain (which is correct) and refuses to move past that dialog. And I cannot "manage" the account because it does not exist so I can't log into it.
How can I delete this account from the PC's local login account? The PC login account was originally created without an online account, and then I logged in to my online account and it got attached. I don't know how the second, broken account got attached, but I get ongoing warnings about it needing to be fixed.
