how to remove yahoo account from this surface pro 7 with windows 11 pro

Hello Granville Cayetano,

Welcome to Microsoft Community.

After reading through the problems you describe here, this is my understanding of your problem:

You signed up for a Microsoft account using Yahoo Mail and used it to log in to this computer. And now you want to remove this account from this computer?

If my guess is what you want now, click on the Start menu -- Settings -- Account --Your info:

Then click on "Log in with local account", after completing this operation, you will be asked to log in with a local account, if you do not have one, you only need to follow the instructions to register a new local account.

Then open Email & accounts, verify that the Microsoft account is still there, and delete it if you can see it.

But if I don't understand your question correctly, please explain your question in detail.

Best Regards,
