Hi Yip Ivan,
I’m following up to see how things went after you tried the steps in the AI Answer. Were you able to remove the old account and can you now sign in normally with the account you want to keep?
If the issue continues, please check whether the old account still appears on the Windows sign-in screen or under Settings > Accounts > Other users, Email & accounts or Access work or school. Please also confirm that the account you are keeping shows Administrator and let me know whether the old profile folder is still present under C:\Users.
If you receive an error or sign-in prompt, please share the exact message and explain when it appears. You may also include a screenshot, but please hide email addresses, usernames, device details, BitLocker recovery keys and other personal information first.
With those details, I can help identify the remaining account connection and advise the most appropriate next step.
