How to remove 2nd Email log in for Windows 11

The delay at the sign-in screen is unlikely to be caused simply by adding a second email address, but the old account can be removed safely once a working sign-in method is confirmed.

To reduce sign-in issues and remove the old email sign-in, follow these steps in order:

1. Confirm a working sign-in method
   1. On the PC, sign in normally (even if it takes a few minutes).
   2. Open Settings > Accounts > Sign-in options.
   3. Under Ways to sign in, make sure at least one method (for example PIN (Windows Hello) or Password) is set up and working for the new email account. If not, set up a PIN or other method and test it by locking the PC and signing back in.
2. Check sign-in settings that might slow login
   1. In Settings > Accounts > Sign-in options:
      • On Windows 11, under Additional settings, review If you've been away, when should Windows require you to sign in again? and choose a reasonable option.
   2. Restart the device once after any changes. Restarting can clear temporary issues that affect sign-in performance.
3. Remove the old Microsoft account from Windows (if it is a separate account on the device) If the old email appears as a separate user on the sign-in screen:
   1. Sign in with the account that should remain.
   2. Open Settings > Accounts > Other users.
   3. Under Other users, select the old account and remove it if it is no longer needed.
4. Remove the old email from “Email & accounts” (if it is only an app/account entry)
   1. Open Settings > Accounts > Email & accounts.
   2. Under Accounts used by email, calendar, and contacts or Accounts used by other apps, select the old email and choose Remove.
5. If the old email is just an alias on the same Microsoft account If both emails belong to the same Microsoft account (aliases), the sign-in delay is not caused by having two aliases. To stop using the old email as a sign-in name without losing access:
   1. Go to Manage how you sign in for the Microsoft account (online) and make the new email the primary alias.
   2. Optionally remove the old alias once the new one is primary and working. This changes only how the account is signed in; it does not delete the Windows profile.

If sign-in is still very slow after these steps, test signing in with a different account on the same device (if available). If another account signs in quickly, review apps or services configured only on the slow account (for example, accounts added under Email & accounts) and remove any that are no longer valid.
