Hello, I'm Louie, and I'm happy to help you today. Hope you're doing well and safe there. I'm sorry that you're having trouble with the email account attached to your pc.
If you're no longer using an account, you can remove it from the Windows 10 settings using these steps:
Open Settings.
Click on Accounts.
Click on Email & accounts.
Select the account that you're planning to remove.
Click the Manage button.
Click the Delete account from this device option.
Click the Delete button.
Click the Done button.
If you need to remove an account for apps, use these steps:
Open Settings.
Click on Accounts.
Click on Email & accounts.
Under the "Accounts used by other apps" section, select the account that you're planning to remove.
Click the Remove button.
Click the Yes button.
After completing the steps, the account information will no longer be available on Windows 10.
Hope this helps.
Kind regards,
Louie
