The quickest way to change your username

Open Settings by pressing the Windows key and typing "Settings," then select it. Go to Accounts in the left menu, then click Your info at the top. You'll see your current username under "Who's using this PC right now?" — click Rename your account and type your new name. Windows will ask you to restart; do that, and the change takes effect when you log back in.

This method works if you remember your password and have administrator rights on the machine. It changes only the display name — the name that appears on the login screen and in the Start menu — not the folder name Windows created when you first set up the account.

The whole process takes about five minutes. You don't need to uninstall programs, move files, or create a new account.

Key Takeaways

  • The Settings app method (Settings > Accounts > Your info > Rename your account) is the fastest way and works for most people in under five minutes.
  • Changing your username in Settings changes only the display name on your login screen, not the hidden folder name Windows uses to store your files.
  • If you don't remember your password or don't have administrator rights, you'll need to use the Control Panel method or create a new account instead.
  • After you rename your account, Windows will ask you to restart — the new name appears after you log back in.
  • Programs and files stay exactly where they are; renaming your account does not move or delete anything.

What the display name actually controls

When you change your username through Settings, you're changing the display name — what shows on your lock screen, your Start menu, and in the top-right corner of Windows. This is the name other people see if they look at your computer, and it's the name that appears in shared folders or when you're connected to a network.

The hidden folder name stays the same. Windows stores your files in a folder like C:\Users\OldName, and renaming your display name does not change that path. This matters only if you're trying to move files between computers or if a program looks for files in a specific user folder — most programs don't, so you won't notice.

If you need to change the actual folder name (which is rare), you have to create a new account, move your files over, and delete the old one. That's a longer process covered below.

Using Control Panel if Settings doesn't work

If the Settings method doesn't open or you're on an older version of Windows 10, you can rename through Control Panel instead. Press the Windows key, type "Control Panel," and open it. Click User Accounts, then click User AccountsChange your account name on the left — click it, type your new name, and click Rename.

This does the same thing as the Settings method: it changes your display name only. The result is identical, and it takes the same amount of time. Use this route if Settings is frozen or not responding on your machine.

Changing the folder name (the longer route)

If you need to change the actual user folder from C:\Users\OldName to C:\Users\NewName, you can't do it while Windows is running. You have to create a new account, copy your files to it, and remove the old one.

First, create a new local account with the name you want. Press the Windows key, type "Settings," go to Accounts, click Family & other users, and select Add someone else to this PC. Choose I don't have this person's sign-in information, then Add a user without a Microsoft account. Give it the name you want and a password.

Log out and log into the new account. Then go back to Settings, return to Family & other users, select your old account, and click Remove. Windows will ask what to do with your files — choose Keep files. Your old user folder will move to the desktop as a folder you can copy from. Move the contents into your new account's folders (Documents to Documents, Pictures to Pictures, and so on), then delete the old folder when you're done.

This method takes 20 to 30 minutes and requires you to move files manually, but it changes the actual folder name that Windows uses.

What happens to your programs and files

Renaming your account through Settings does not touch your programs or files. Everything stays in the same place, and every program continues to work. Your email, browser bookmarks, game saves, and documents are all still there after you restart.

If you use the longer method (creating a new account and moving files), programs may need to be reinstalled because they store settings in your user folder. You can copy the files, but the programs themselves usually need a fresh install on the new account. This is another reason most people use the quick Settings method instead.

If you're locked out of your account

If you don't remember your password, you can't change your username through Settings or Control Panel — both require you to log in first. You have two options: reset your password through the login screen, or create a new administrator account from another device.

At the login screen, click I forgot my password and follow the recovery steps (usually a security question or a code sent to your email or phone). Once you're back in, you can rename your account normally. If you can't recover your password, you'll need to create a new account on the machine and use that one instead.

Frequently Asked Questions

Will changing my username break my programs or games?

No. Programs and games don't care what your display name is. They'll run exactly as they did before. If you use the longer method of creating a new account and moving files, some programs may need to be reinstalled, but the quick Settings method leaves everything untouched.

Can I change my username to something with special characters or spaces?

Yes, the display name can include spaces, numbers, and most special characters. The hidden folder name (if you ever need to change it) has stricter rules — it can't have certain symbols like asterisks or question marks — but the display name is flexible.

Do I need to restart Windows after I change my username?

Windows will prompt you to restart, and you should do it. The new name appears after you log back in. You can save your work and close programs first, but the restart is necessary for the change to take full effect.

What's the difference between a local account and a Microsoft account username?

A local account is stored only on your computer; changing its name changes what appears on your login screen. A Microsoft account is tied to your email and syncs across devices. If you use a Microsoft account, changing your display name in Settings changes the name on that computer only, not your Microsoft account itself.

Can I change my username if I'm not the administrator?

No. You need administrator rights to rename an account. If you don't have them, ask whoever set up the computer to change it for you, or create a new administrator account if you have access to one.
