The quickest way: Settings menu

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. You'll see your current username displayed under your profile picture. Click the Rename your account button below it.

Type your new username in the box that appears. Windows will ask you to confirm the change. Click Next, then Finish. You'll need to sign out and sign back in for the change to take effect — Windows will prompt you to do this automatically.

This method works for local accounts (usernames stored only on your computer) and Microsoft accounts (usernames linked to your Microsoft email). The process is identical for both.

Key Takeaways

  • The Settings app is the fastest way to rename your account — it takes about two minutes and requires no restart.
  • Your username change takes effect the next time you sign in, so you'll need to log out and back in.
  • If you use a Microsoft account, changing your username in Settings changes only the display name on your computer, not your email address.
  • Files and folders you created before the change will still be there after — Windows updates the permissions automatically.
  • If the Rename button doesn't appear, your account may not have administrator rights, and you'll need to use Control Panel instead.

What happens to your files and folders

Your documents, downloads, desktop, and pictures all stay where they are. Windows keeps track of your files by a hidden identifier, not by your username, so renaming your account doesn't move or delete anything. You'll still see all your files in the same places.

The folder path on your hard drive (like C:\Users\YourName) does not change when you rename your account. If you need to access files through that path in a program or command line, you'll still use your old username. This is a technical detail that rarely matters unless you're writing batch files or scripts.

If the Settings method doesn't work

If you don't see a Rename your account button, your account may not have administrator rights. Right-click the Settings app and choose Run as administrator, then try again. If that doesn't work, use Control Panel instead.

Open Control Panel by pressing the Windows key and typing "Control Panel." Go to User Accounts, then click User AccountsManage another account, select your account from the list, then click Change the account name. Type your new username and click Rename.

Changing a Microsoft account display name

If you sign in with a Microsoft account (one tied to an email address like yourname@outlook.com), the Settings method changes only the display name on your computer. Your email address and Microsoft account username stay the same. This is usually what you want — it lets you change how your name appears without affecting your email or cloud storage.

If you need to change your actual Microsoft account username or email, you'll do that through your Microsoft account settings online, not through Windows. Go to account.microsoft.com, sign in, and look for Your info or Account settings. Changes there take a few hours to sync to your computer.

Renaming a local account

A local account is one that exists only on your computer — it's not connected to an email address or Microsoft services. If you use a local account, the Settings method works exactly the same way, and your new username takes effect when ready after you sign back in.

Local accounts are less common now because Windows pushes users toward Microsoft accounts during setup. If you're not sure which type you have, open Settings and go to Accounts > Your info. If you see an email address under your name, you have a Microsoft account. If you see only a username, you have a local account.

What you should know about usernames and security

Changing your username does not affect your password. You'll still sign in with the same password you used before — only the name displayed on the sign-in screen changes. If you want to change your password at the same time, you can do that in Settings under Accounts > Sign-in options > Password.

Your username is visible to anyone who uses your computer or looks at your file permissions, so choose something you're comfortable with others seeing. It's not a security credential the way a password is — it's more like a label. Changing it won't make your computer more or less find.

Frequently Asked Questions

Will changing my username affect my programs or games?

No. Programs and games don't depend on your username — they depend on your user account existing. After you rename your account and sign back in, everything will work the same way. Your installed programs, game saves, and settings will all be there.

Can I change my username without signing out?

You can make the change in Settings without signing out, but the new username won't take effect until you sign out and sign back in. Windows will remind you to do this. You can't use the new username to sign in until you've completed the sign-out and sign-in cycle.

What if I forgot my password and can't sign in to change my username?

You'll need to reset your password first. If you use a Microsoft account, go to account.microsoft.com on another device and use the password reset option. If you use a local account, you'll need to use another administrator account on the computer to reset it, or use Windows password recovery tools.

Does changing my username change my email address?

No. If you sign in with a Microsoft account, your email address stays the same. Your username change only affects the display name on your computer. Your email, OneDrive, and other Microsoft services remain unchanged.

Can I change my username back to what it was before?

Yes. Use the same Settings method or Control Panel method to rename it again. There's no limit to how many times you can change your username. Just remember to sign out and back in for each change to take effect.
