To give the second account administrator rights and then remove the first account, use the built‑in account management in Windows.
- Sign in with the current administrator account (the one that already has admin rights). Changing account types requires an admin.
- Open the Settings app on the laptop.
- Go to Accounts > Other users (or Family & other users, depending on the exact Windows 11 build). You can also use this shortcut: Other Users.
- Under Other users, select the account that has the up‑to‑date email address.
- Select the flyout for that account, then next to Account options, choose Change account type.
- In the dropdown, change the account type from Standard user to Administrator, then select OK.
After confirming that the second account now has administrator rights and can sign in successfully:
- Still signed in as an administrator, go back to Settings > Accounts > Other users.
- Select the first Microsoft account (the one with the unused email) under Other users.
- Use the available option to remove that account from the device. This will remove that user profile and its local data from the PC.
Important: Administrators have complete control over the system (install software, change settings, access all files). Limit the number of admin accounts to reduce security risks and use standard accounts for day‑to‑day work.
If the account to be removed is the one currently used to sign in to Windows (the primary sign‑in account), it cannot be removed directly from there. In that case, first ensure the new admin account is created and working, sign in with it, and then remove the old one as described.
