The quickest way: Settings on Windows 10 and 11

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 will see your current username displayed. Click the blue Rename your account button, type your new username, and click Next. Windows will ask you to confirm — click Finish, and the change takes effect when ready.

This method works on any Windows 10 or 11 machine where you have administrator rights. You do not need to restart your computer. The new name appears the next time you sign in, and it shows up in the Start menu, File Explorer, and anywhere else Windows displays your account name.

Key Takeaways

  • The Settings method (Accounts > Your info > Rename your account) is the fastest route and works on Windows 10 and 11 without restarting.
  • Your username and your sign-in name are separate — changing the username does not change the email or password you use to log in.
  • If you do not have administrator rights on your computer, you will need to ask someone who does to make the change for you.
  • Changing your username does not affect your files, programs, or settings — everything stays where it is.

What changes and what stays the same

When you change your username, Windows updates the display name everywhere you see it: your Start menu, your user folder in File Explorer, your lock screen, and any shared computers that show a list of users. Your files remain in the same location and stay accessible to you.

Your sign-in credentials do not change. If you sign in with a Microsoft account (an email address), that email and password stay the same. If you sign in with a local account (a username and password created on just this computer), your password stays the same — only the display name changes. Programs you have installed continue to work normally.

If you forgot your administrator password

You cannot change your username without administrator rights. If you are the only person who uses the computer and you have forgotten the administrator password, you have two options: reset the password through your Microsoft account, or create a new local administrator account.

If you sign in with a Microsoft account, go to the Windows sign-in screen, click I forgot my password, and follow the steps to reset it using your recovery email or phone number. If you sign in with a local account and have no recovery option, you will need to use another administrator account on the computer, or contact Microsoft Support for further help.

Changing your username on older Windows versions

Windows 7 and earlier versions use a different path. Right-click This PC or My Computer on your desktop, select Manage, then go to Local Users and Groups > Users. Right-click your account name and select Rename. Type the new name and press Enter.

Some older systems may require you to restart after renaming. The same rule applies: your files and programs are not affected, and your sign-in password stays the same.

Why your username and sign-in name are different things

Windows treats your display username (what you see in the Start menu) separately from your sign-in credentials (the email or password you type to log in). This separation exists because multiple people can use one computer, and each person has their own display name and their own sign-in method.

If you change your display username, your sign-in email or password does not change. If you want to change the email address you use to sign in to a Microsoft account, that is a different process done through your Microsoft account settings online, not through Windows Settings.

What to do if the rename button does not appear

If you do not see the Rename your account button in Settings, you may not have administrator rights on this computer. Ask the person who set up the computer to make the change for you, or to give you administrator rights first.

On some work or school computers, the administrator may have locked down the ability to change usernames. If that is the case, contact your IT department or help desk — they control the policy and can either change it for you or explain why it is restricted.

Frequently Asked Questions

Will changing my username affect my Microsoft account or email?

No. Your display username and your Microsoft account are separate. Changing your Windows username does not change the email address you use to sign in or any settings in your Microsoft account online.

Do I need to restart Windows after changing my username?

No. The change takes effect when ready on Windows 10 and 11. You will see the new name in the Start menu and File Explorer right away, and it appears on your lock screen the next time you sign in.

What happens to my user folder if I change my username?

Your user folder (C:\Users\YourName) keeps its original name. Windows displays your new username in File Explorer, but the folder path does not change. Your files stay in the same place and remain accessible.

Can I change my username if I am not the administrator?

No. You need administrator rights to change a username. If you are not an administrator, ask the person who set up the computer to make the change or to give you administrator rights first.

What if I want to change my sign-in password instead of my username?

Press Ctrl + Alt + Delete on your keyboard, select Change a password, and follow the prompts. This changes what you type to log in, not your display name.
