one of the IDs was saved misspelled
Not sure exactly what you mean by "IDs".....
would that be an account name, which we commonly refer to as a user name?
IS it a local account or a Microsoft account"
I did that once, carelessly setting up a brand new laptop for my daughter-in-law. Misspelled her name when local account was created and then to further complicate the issue I linked it to a Microsoft account.
What a pain.
IF I remember correctly, I think I ended up creating a separate admin user account logged in with that account, removed the initial account and started that one from scratch without the misspelling and then deleted the new local admin account that I created to do this.
Generally speaking all "credentials" are kept by the Credential Manager applet in the Control Panel, (web and windows credentials).
Not sure if that information will help you at all though, as I'm not sure I understand completely..... your problem.
