Microsoft administrator- My administrator changed to a Gmail account I want my Yahoo mail account for administrator. How can I change it back?

Change the existing Windows administrator’s primary Microsoft-account alias to the Yahoo address if you want to keep the same Windows profile, files, settings, and applications.

Keep the current Windows profile and change its displayed email

First identify the account type:

1. Open Settings > Accounts > Your info.
2. If the Gmail address appears above Administrator, Windows is using a Microsoft account.
3. If no email address appears, it is a local account rather than a Gmail-linked Microsoft account. Microsoft documents this distinction in the Windows account details.^1^

If Gmail appears:

1. Sign in to the Microsoft account currently associated with Gmail.
2. Open Your info > Manage how you sign in to Microsoft.
3. Select Add email.
4. Enter the Yahoo address as an existing email address.
5. Complete any requested verification.
6. Select Make primary beside the Yahoo address.

A Yahoo address can be used as a Microsoft-account alias. Changing the primary alias keeps the same Microsoft account, password, storage, subscriptions, and settings; the primary alias is the address displayed on devices.^2^ ^3^

Do not remove the Gmail alias until the Yahoo address works for Microsoft sign-in. Removing an alias does not repair or restore the separate Yahoo mailbox.

If the Yahoo address cannot be added

A Yahoo mailbox and a Microsoft account registered with a Yahoo address are separate accounts. First try signing in to the Microsoft account using the Yahoo address and its Microsoft-account password, which might differ from the Yahoo mailbox password.

• If that sign-in works: the Yahoo address already belongs to a Microsoft account and cannot also be added as an alias to the Gmail-linked account. Aliases cannot be transferred or used to combine two Microsoft accounts.^4^
• If the Microsoft password is unavailable: submit Microsoft’s account recovery form. This recovery attempt does not require access to the Yahoo mailbox.^5^
• If Microsoft requests a code sent to Yahoo: recover the mailbox through Yahoo’s official Sign-in Helper. Microsoft Support cannot restore a Yahoo mailbox.
• Microsoft’s sign-in helper and Contact Support are additional options, but support agents cannot send password-reset links or manually change protected account details.^2^

Use the Yahoo-linked account as a separate administrator

Choose this route if Yahoo already belongs to a different Microsoft account. This creates a separate Windows profile; it does not rename or convert the existing Gmail profile.

After recovering the Yahoo-linked Microsoft account:

1. While signed into the existing administrator, open Settings > Accounts > Other users.
2. Select Add account and enter the Yahoo-linked Microsoft-account credentials.
3. Under Other users, expand the new account.
4. Select Change account type.
5. Choose Administrator, then select OK.
6. Select Start > account picture > Switch user, and sign in to the Yahoo-linked account.

These are the supported Windows 11 steps for adding a user and assigning administrator privileges.^6^

Do not remove the Gmail Windows user until the Yahoo user opens successfully and any required personal files have been copied. Removing a Windows user also removes that profile’s data from the device.^6^

If Windows shows a local administrator

If Settings > Accounts > Your info shows no email address, the current administrator is local. Add the recovered Yahoo-linked Microsoft account through Settings > Accounts > Other users > Add account, then promote it to Administrator using the steps above. This again creates a separate profile rather than changing the local profile’s identity.
