Change Your Account Name in Windows or macOS

The fastest way to change the name on your computer is to rename your user account through your operating system's settings. On Windows, this takes about two minutes. On macOS, it takes slightly longer because you may need to create a new account, but both methods are straightforward and don't require restarting your machine or calling support.

Your account name is what appears on your login screen and in file paths. Changing it does not affect your files, passwords, or installed programs — they all stay exactly where they are. The name change applies only to how your account displays in Windows or macOS.

Key Takeaways

  • Windows lets you rename your account directly through Settings > Accounts > Your Info, and the change takes effect when ready.
  • macOS does not have a direct rename option; you must create a new account and transfer files, or use Terminal commands if you are comfortable with command-line tools.
  • Your files, programs, and passwords remain unchanged when you rename your account.
  • If you use Microsoft or Apple ID sign-in, your account name and your ID name are separate — changing one does not change the other.
  • Some programs store file paths using your old account name, so you may see the old name in those paths even after renaming.

Renaming Your Account in Windows 10 or 11

Open Settings by pressing the Windows key and typing "Settings", then select the Settings app. Go to Accounts on the left sidebar, then select Your Info. You will see your current account name displayed at the top of the page.

Click the Rename your account button. Type your new name in the box that appears, then click Next. Windows will ask you to confirm; click Finish. The change takes effect when ready, and you will see your new name on the next login screen.

If you do not see a "Rename your account" button, you may be using a Microsoft account rather than a local account. Microsoft accounts are tied to your email address, and renaming works differently — see the section below on Microsoft and Apple ID accounts.

Renaming Your Account in macOS

macOS does not have a built-in rename function for existing accounts. Your two main options are to create a new account and transfer your files, or to use Terminal if you are comfortable with command-line tools.

Option 1: Create a new account and transfer files. Go to System Settings (or System Preferences on older versions), then select General > Users & Groups (or just Users & Groups). Click the lock icon at the bottom left and enter your password. Click the plus sign to create a new account, choose Administrator as the account type, and enter your desired name. Log out of your current account, log into the new one, then use Migration Assistant (in Applications > Utilities) to transfer your files from the old account. Once everything is moved, you can delete the old account.

Option 2: Use Terminal. If you are comfortable with command-line tools, you can rename your account folder and update the system database without creating a new account. This is faster but requires typing specific commands. Search for "Terminal" in Spotlight, open it, and follow Apple's official documentation for the dscl command to rename your account. If you are unsure about this method, the first option is safer.

Changing Your Microsoft or Apple ID Display Name

If you sign into Windows with a Microsoft account or macOS with an Apple ID, you have two separate names: your account name (what appears on your computer) and your ID display name (what appears in Microsoft or Apple services). Changing one does not change the other.

To change your Microsoft account display name, go to account.microsoft.com, sign in, and select Your Info. Click Manage your Microsoft account, then edit your name. This change appears in Outlook, OneDrive, and other Microsoft services, but may not when ready update on your Windows login screen — Windows may continue showing your old account name until you restart.

To change your Apple ID display name, go to appleid.apple.com, sign in, select Personal Information, and edit your name. This updates how your name appears in iCloud, the App Store, and other Apple services. Your macOS account name remains separate unless you also rename it through System Settings.

What Happens to Your Files and Programs

Renaming your account does not move or delete any of your files. Your Documents, Desktop, Downloads, and other folders stay in the same place with all their contents intact. Programs you have installed continue to work normally.

However, some programs store file paths using your old account name. For example, a shortcut might point to "C:\Users\OldName\Documents\file.txt". After you rename your account to NewName, that path may still show "OldName" in the program, even though the file is actually in the correct location. Windows and macOS handle this behind the scenes, so the program still finds the file — you just see the old name in the path. If this bothers you, you can manually update shortcuts or reinstall the program, but it is not necessary.

When to Call a Professional

Renaming your account is safe and does not require professional help. However, if you are unsure about using Terminal on macOS, or if you have a work computer managed by your employer's IT department, check with your IT team before making changes — they may have policies about account names or may need to update their records.

If you cannot find the rename option in your Settings, or if you are locked out of your account, contact your computer manufacturer's support line or your IT department. Do not attempt to rename the account through file system changes or registry edits unless you have specific guidance from a professional.

Frequently Asked Questions

Will renaming my account affect my password?

No. Your password remains the same and continues to work on your login screen. The account name and password are separate — changing the name does not reset or change your password.

Can I change my account name back to the old one?

Yes. Follow the same steps you used to rename it the first time. You can change your account name as many times as you want.

What if I have a work computer?

Check with your IT department or manager before renaming your account. Some workplaces manage accounts through a network domain, and renaming may conflict with company policies or cause issues with shared files and email.

Does renaming my account change my email address?

No. Your email address is separate from your account name. If you sign in with a Microsoft or Apple ID, your email stays the same even after you rename your account on the computer.

What if the rename button does not appear in Windows Settings?

You are likely using a Microsoft account instead of a local account. Microsoft accounts are tied to your email address and cannot be renamed through Settings. You can change your display name through your Microsoft account online, but your Windows login name will remain your email address.
