Change Your User Name in Windows or Mac Settings

You can change the name that appears on your computer's login screen and in system menus through your operating system's settings. The exact steps depend on whether you use Windows or Mac, but both let you rename your account without losing files or programs. The process takes about five minutes and requires you to be logged in as an administrator.

On Windows 11 or 10, go to Settings > Accounts > Your info, then click Rename your account. Type the new name you want and click Next, then Finish. Your computer will ask you to sign out and back in before the change takes effect.

On Mac, open System Settings > General > About, then click Edit next to the computer name at the top. Type your new name and press Return. This changes the name other computers see on your network. If you want to change the account name itself (what appears on the login screen), go to System Settings > General > Users & Groups, right-click your account, select Advanced Options, and change the Full Name field.

Key Takeaways

  • Windows users can rename their account through Settings > Accounts > Your info by clicking Rename your account and entering the new name.
  • Mac users can change the computer name in System Settings > General > About, or change the account name through Users & Groups > Advanced Options.
  • You must be logged in as an administrator to change either your account name or your computer's network name.
  • The change takes effect when ready on Mac but requires you to sign out and back in on Windows.
  • Changing your user name does not affect your files, programs, or saved passwords.

What Happens to Your Files and Programs

Your files, documents, photos, and installed programs remain exactly where they are. Windows and Mac both update the folder path behind the scenes so your computer still knows where everything is stored. You will not lose access to anything, and your programs will continue to work without reinstalling them.

Your saved passwords, browser history, email accounts, and other settings stay in place as well. The only thing that changes is the name displayed on the login screen and in system menus. If you have cloud storage set up (OneDrive, iCloud, Google Drive), it will continue to sync normally.

Changing Your Account Name vs. Your Computer Name

Windows and Mac both have two different names you might want to change. Your account name is what appears on the login screen and in the Start menu or Apple menu. Your computer name is what other devices see when you share files over a network or connect to a printer.

Most people only need to change their account name. Change the computer name only if you want other people on your network to see a different name when they browse shared folders or connect devices. On Windows, you can change the computer name through Settings > System > About > Rename this PC. On Mac, the computer name is changed in the same place as the account name (System Settings > General > About).

If You Forgot Your Administrator Password

You cannot change your user name without administrator access. If you are locked out of an administrator account, you will need to reset the password first. On Windows, restart your computer and select I forgot my password on the login screen, then answer your security questions. On Mac, restart and hold Command + Q on the login screen to open password reset options.

If neither of those options work, you may need to use a second administrator account on the same computer, or contact your IT department if this is a work computer. For personal computers, you can also create a new administrator account through Settings (Windows) or System Settings (Mac) and use that to change the original account name.

Common Mistakes to Avoid

Do not use special characters like asterisks, question marks, or forward slashes in your new user name. Windows and Mac both restrict certain symbols because they can interfere with file paths and network sharing. Stick to letters, numbers, spaces, and hyphens.

Do not change your account name while programs are running or while files are being synced to the cloud. Close everything first, wait a few seconds, then make the change. If you interrupt the process, your computer may have trouble finding your files.

Do not assume that changing your user name will change your Microsoft account name (Windows) or Apple ID (Mac). Your user name and your online account are separate. If you want to change your Microsoft or Apple account name, you will need to do that through their websites instead.

Changing Your Name on a Work or School Computer

If your computer is managed by an employer or school, you may not have permission to change your user name. Work and school computers are often locked down by IT administrators who control what users can modify. Try going through the normal settings steps first — if you do not see a rename option, your account does not have that permission.

Contact your IT department or help desk to request a name change. They can change it for you on their end, and the change will sync to your computer the next time you restart. Do not try to work around restrictions, as this can cause your account to stop working properly.

Frequently Asked Questions

Will changing my user name affect my email or Microsoft/Apple account?

No. Your user name on your computer is separate from your email address and online account. Changing your computer user name will not change your email or sign-in credentials for Microsoft, Apple, Google, or any other service.

Can I change my user name without restarting my computer?

On Mac, the change takes effect when ready. On Windows, you must sign out and sign back in for the new name to appear everywhere, though you do not need a full restart. Close your programs, sign out, and sign back in.

What if I want to change my user name back to the old one?

You can change it as many times as you want using the same steps. Go back to Settings (Windows) or System Settings (Mac) and rename it again. There is no limit to how many times you can do this.

Does changing my user name affect my WiFi or network password?

No. Your WiFi password and network settings are stored separately from your user name. You will stay connected to the same networks without having to re-enter passwords.

Can I have spaces or special characters in my new user name?

Spaces are fine, but avoid special characters like asterisks, question marks, colons, and forward slashes. These can cause problems with file paths and network sharing. Letters, numbers, spaces, and hyphens work best.
