Windows 10: How do you remove a microsoft email/account from my system?

A long time ago my friend borrowed my pc and signed in to the Xbox app. Now I keep getting notifications that I changed my password on this account. I can't figure out how to remove his Microsoft account from my pc without his password.

Remove account

I suggest you backup your personalized files first before removing the account.
To delete an account, follow these steps:

1. Press WIN + X keys and click Command Prompt (Admin) from the menu.
2. Type the following command and press Enter. Replace test with the name of your sister's account. Code:

 

Unauthorized Emails from my account?

It is more than likely that your email account was hacked, either by a virus sniffing your password, or just simply hacked.

Either way, change your password on your email account. Unfortunately the damage by already be done. They already have your contact list and your email address associated with that contact list. There is nothing stopping them from sending out emails using their own SMTP servers to everyone on your contact list and claiming the emails are from your email address. They don't actually have to have access to your yahoo account or even any yahoo server to send emails to people that come from your address.
