The fastest way to change your username

Open Settings by pressing the Windows key and typing "settings", then select the Settings app. Go to Accounts in the left menu, then click Your info. At the top of the page you'll see your current username. Click the Rename button next to it, type your new username, and click Next. Windows will ask you to sign out and back in — do that, and your username is changed.

This method works for any account type and takes about two minutes. The new username appears when ready after you sign back in, on your lock screen, in the Start menu, and in File Explorer's user folder. If you're changing the username on someone else's account on your PC, you'll need to be signed in as an administrator.

If the Rename button is greyed out or missing, your account is managed by your workplace or school. Contact your IT department — they control username changes for those accounts, and you won't be able to change it yourself through Settings.

Key Takeaways

  • The Settings app is the standard way to change your username in Windows 11, and it takes about two minutes from start to finish.
  • Your new username shows up everywhere when ready after you sign out and back in — on the lock screen, Start menu, and in your user folder.
  • If your account is managed by your workplace or school, the Rename button will be unavailable and you'll need to contact your IT department instead.
  • Changing your username does not affect your files, passwords, or installed programs — everything stays exactly where it is.
  • If you forget to sign out after renaming, Windows will prompt you to do so the next time you restart your PC.

What happens to your files and folders when you rename

Your user folder — the one that contains your Documents, Downloads, Desktop, and Pictures — keeps its old name. If your old username was "Sarah" and you change it to "SarahM", your folder stays named "Sarah" in the path C:\Users\Sarah. This is intentional and does not cause problems. Windows knows which folder belongs to your account regardless of what you call yourself on the login screen.

All your files, shortcuts, and program settings remain untouched. Your passwords stay the same. Programs you've installed continue to work. The only visible change is what appears on your lock screen and in the Start menu when you hover over your profile picture.

If you're concerned about the mismatch between your display name and your folder name, you can rename the folder itself through File Explorer, but this is optional and not necessary for anything to work correctly. Most people leave the folder name alone.

Changing a different account's username on your PC

If you need to change someone else's username and you're the administrator on the PC, sign in to your own account first. Open Settings, go to Accounts, then click Other users in the left menu. Find the account you want to change and click it. Click Rename, type the new username, and click Next. That person will see the change the next time they sign in.

You do not need their password to change their username. However, if their account is password-protected, they'll still need their password to sign in after the change — the username change does not affect their login credentials.

If you don't see the Other users option or the account you're looking for, you may not have administrator rights on this PC. Check with whoever set up the computer, or try signing in to an account that has administrator status.

When the Settings method doesn't work

If you click Rename and nothing happens, or if the button is greyed out, the most common reason is that your account is managed by your workplace, school, or organization. These accounts are linked to a domain or Microsoft Entra ID, and only the organization's IT team can change the username. Contact your IT department or help desk and they'll make the change for you.

If you're using a local account (not connected to a Microsoft account or organization), and the Rename button still doesn't appear, try signing out completely and signing back in, then returning to Settings. Sometimes a temporary glitch prevents the button from showing until you refresh your session.

Another rare cause is that your account has restrictions set by parental controls or group policy. If you're the administrator and still can't rename the account, open the Local Users and Groups tool by pressing Windows key + R, typing "lusrmgr.msc", and pressing Enter. Find your account in the list, right-click it, select Rename, and type the new name. This method bypasses the Settings interface and works when Settings is blocked.

Using Local Users and Groups for more control

The Local Users and Groups tool gives you direct access to account settings and is useful if Settings isn't responding or if you need to rename an account that Settings won't let you touch. Press Windows key + R, type "lusrmgr.msc", and press Enter. You may see a User Account Control prompt asking for permission — click Yes.

In the window that opens, click the Users folder on the left. You'll see a list of all accounts on your PC. Right-click the account you want to rename and select Rename. Type the new username and press Enter. The change takes effect the next time that person signs in.

This method works the same way as Settings — it changes only the display name, not the user folder. Use it only if Settings is not working or if you need to rename an account that Settings won't let you change. For most people, the Settings method is simpler and faster.

Renaming your Microsoft account versus your local account

Windows 11 lets you sign in with either a Microsoft account (which uses an email address) or a local account (which uses a username you create). The method to change your username is the same either way — go to Settings, Accounts, Your info, and click Rename. However, what you're actually changing is different.

If you sign in with a Microsoft account, you're changing the display name that appears on your PC, not your email address or your Microsoft account itself. Your email stays the same, and you still sign in with that email. The display name change affects only this PC.

If you sign in with a local account, you're changing the username you type at the login screen. This is the name that appears everywhere on your PC, and it's the only name associated with your account.

If you want to change your actual Microsoft account email or details, you need to visit the Microsoft account website, not Windows Settings. Settings only controls what shows up on your PC.

Frequently Asked Questions

Will changing my username affect my Microsoft account or email?

No. If you sign in with a Microsoft account, changing your username in Settings only changes the display name on your PC. Your email address and Microsoft account stay exactly the same. You still sign in with your email, and nothing changes on other devices or in Microsoft services.

Do I need to restart my PC after changing my username?

Windows will ask you to sign out and back in when ready after you rename. You do not need a full restart. Sign out, sign back in with your password, and the change is complete. If you skip signing out, Windows will prompt you to do so the next time you restart.

Can I change my username back to the old one?

Yes. Go back to Settings, Accounts, Your info, click Rename, and type your old username. The process is identical. There's no limit to how many times you can change it.

What if I change my username and then forget what it was?

Look at your lock screen or your user folder in File Explorer. Your current username appears on the lock screen above the password field. In File Explorer, open "This PC" and look in the address bar when you navigate to your user folder — the path shows your current username.

Does changing my username affect my passwords or saved logins?

No. Your passwords, saved WiFi networks, browser logins, and program settings all stay exactly as they were. The username change is purely cosmetic — it changes only what appears on your screen, not how your account works or what you can access.
