What you're changing and why it matters

Your computer's user account name is the label that appears on your login screen and in file folders. Changing it does not affect your password, your files, or your ability to log in — it only changes what the system calls you. Windows and Mac both let you do this in settings, though the steps differ between them.

The most common reason to change your account name is that it no longer matches how you want to be identified. You might have married, divorced, or simply chosen a different name. You might also want to change a name that was set up by someone else — like a parent or IT administrator — to something you prefer.

One important note: changing your account name in settings does not rename your user folder on disk. That folder stays the same to protect your files and settings. This is normal and does not cause problems.

Key Takeaways

  • Windows and Mac both let you change your account name through Settings without affecting your files or password.
  • On Windows, you change the name in Settings under Accounts, and the change takes effect immediately.
  • On Mac, you change the name in System Settings under General, and you may need to restart to see the change everywhere.
  • Your user folder on disk keeps its original name — this is intentional and does not cause problems.
  • If you cannot access Settings because you forgot your password, you will need to reset your password first.

How to change your account name on Windows 10 or 11

Open Settings by pressing the Windows key and typing "Settings", then press Enter. Click on "Accounts" in the left sidebar. You should see your current account name at the top of the page under "Your info".

Click the "Rename your account" button. A dialog box will appear with your current name highlighted. Delete the old name and type the new one. Click "Next", then "Finish". Your new name takes effect immediately — you will see it on the login screen the next time you restart, and in the Start menu right away.

If you do not see a "Rename your account" button, you may be using a Microsoft account instead of a local account. For a Microsoft account, you will need to change your name through your Microsoft account settings online, not through your computer. Go to account.microsoft.com, sign in, and look for "Your info" or "Edit profile" to change the name associated with your account.

How to change your account name on Mac

Click the Apple menu in the top-left corner and select "System Settings" (or "System Preferences" on older versions). Click "General" in the sidebar, then look for "About" at the top. You will see your computer name here, but this is not your user account name — scroll down to find "Users & Groups" or go back and click "Users & Groups" directly in the sidebar.

You may see a lock icon at the bottom of the Users & Groups window. If it is locked, click it and enter your password to unlock it. Right-click your account name in the list on the left and select "Advanced Options". Find the field labeled "Full Name" and change it to what you want. Click "OK" to save the change.

Your new name takes effect immediately in most places, though you may need to restart your computer to see the change in all applications. The change appears in the login screen, the Apple menu, and in file properties right away.

What happens to your files and folders

Your user folder — the one that holds your Documents, Downloads, Desktop, and other personal folders — keeps its original name. This is by design. Renaming the account name in settings does not rename the folder because doing so can break file permissions and cause applications to lose track of where your files are stored.

You will not notice this in everyday use. When you open Finder on Mac or File Explorer on Windows, your folders appear in the normal places. The folder name only matters if you are looking at the path in the address bar or if you are troubleshooting something technical. If you need the folder name to match your new account name for a specific reason, you will need to contact your IT support or use advanced tools — this is not something to do on your own.

If you cannot access Settings to make the change

If you forgot your password and cannot log in, you will need to reset it before you can change your account name. On Windows, use another administrator account to reset your password, or use the password reset disk if you created one. On Mac, use another administrator account or your Apple ID to reset your password through the login screen.

If you are the only account on the computer and you cannot remember your password, you will need to use your computer's recovery mode. On Windows, restart and press F8 or Shift+F8 during startup to reach the recovery menu. On Mac, restart and hold Command+R to enter Recovery Mode. Both processes are technical and may require help from someone with experience — if you are stuck, contact Apple Support or Microsoft Support directly.

Changing the name on a work or school computer

If your computer is managed by an employer or school, you may not be able to change your account name yourself. Many organizations lock this setting to keep accounts consistent across their network. If you try to change it and see a message saying the setting is managed or restricted, contact your IT department or help desk — they can change it for you or explain why it cannot be changed.

The same applies if your computer is part of a domain or uses Active Directory. These are network systems that control accounts from a central location. Your local Settings will not let you change the name because the name is controlled elsewhere.

Frequently Asked Questions

Will changing my account name affect my password?

No. Your password stays exactly the same. You log in with the same password you used before — only the name displayed changes. If you want to change your password at the same time, you can do that separately in Settings under Accounts or Users & Groups.

What if I change my mind and want to change it back?

You can change your account name as many times as you want using the same steps. There is no limit to how many times you can do this. Just go back to Settings or System Settings and follow the same process with your new name.

Does changing my account name affect my email or Microsoft account?

No. Your email address and Microsoft account stay the same. Changing your computer account name only changes what appears on your computer. If you use a Microsoft account to sign in, your email address is still your email address — the display name on your computer is separate.

Will my programs still work after I change my account name?

Yes. Your programs do not care what your account name is. They will continue to work exactly as before. You will not need to reinstall anything or enter new passwords for your programs.

Can I change my account name without restarting?

On Windows, the change takes effect immediately without a restart. On Mac, the change usually takes effect right away, but some applications may not show the new name until you restart. Restarting is not required but may help if you notice the old name still appearing somewhere.
