To remove another administrator and fix the wrong email showing on the account, two things are needed:
- Ensure access to an administrator account that is controlled personally.
- Then remove or downgrade the brother’s account and correct the Microsoft account/email association.
If the current account is corrupted or misconfigured, creating a new administrator account may be required first.
1. Create a new local administrator account (if needed)
If there is no administrator account that is personally controlled, create a new one and make it an administrator:
- Open Settings > Accounts.
- Go to Other users (or use this shortcut: Other Users).
- Add a new user account (see “Manage User Accounts in Windows” for details on adding accounts).
- After creating it, under Other users, select the flyout for the new account.
- Next to Account options, select Change account type.
- From the dropdown, choose Administrator, then select OK.
Sign out and sign in with this new administrator account.
2. Remove or downgrade the brother’s account
Once signed in as an administrator that is personally controlled:
- Open Settings > Accounts > Other users (or Other Users).
- Under Other users, select the flyout for the brother’s account.
- To completely remove it from the device, select Remove next to Account and data.
- Note: This removes his sign-in information and data from the device, but does not delete his Microsoft account itself.
- Alternatively, if the account should remain but without admin rights, select Change account type and switch it from Administrator to Standard user, then select OK.
3. Fix the email/Microsoft account on the personal profile
If the Windows sign-in account is showing the brother’s email instead of the correct one, either:
- Switch from his Microsoft account to a local account, then sign in with the correct Microsoft account; or
- Change which Microsoft account is associated with the profile.
Useful options that can be changed on a Microsoft account include:
- Display name
- Administrator name
- Which email addresses can be used to sign in
- Which email addresses can be used to send email (aliases)
See “What can I change on my Microsoft account?” for details on changing sign-in email addresses and aliases.
If the current Windows profile is badly mixed with his account, another option is:
- Create a new local user account for personal use.
- Make it an administrator (as in step 1 above).
- Sign in with that account and, if desired, convert it to the correct Microsoft account.
- Copy personal files from the old profile to the new one:
- Sign in with the new account.
- Open File Explorer and go to This PC > C: > Users.
- Open the folder for the old user (for example,
C:\Users\Old_Username).
- Select all files and folders and copy them.
- Paste them into
C:\Users\New_Username.
- Do not change File Explorer view options to show hidden or protected system files while doing this.
- After confirming everything is copied, remove the old account from Settings > Accounts > Other users.
If a Microsoft account is used for the new profile, ensure it is the correct personal email and not the brother’s.
