The quickest way to change your username

Open Settings, go to Accounts, select Your info, and click the "Rename your account" button. Windows will ask you to confirm the change, and your new username takes effect the next time you sign in. The whole process takes about two minutes and requires no restart.

This method works on Windows 10 and Windows 11. If you are using a Microsoft account (the kind that syncs across devices), the change appears on all your Windows machines within a few hours. If you are using a local account (one that exists only on this computer), the change happens when ready on just this device.

Key Takeaways

  • The Settings app method is the fastest route: Settings > Accounts > Your info > Rename your account.
  • Your new username takes effect when you sign out and back in — no restart needed.
  • Changing your username does not affect your files, passwords, or installed programs.
  • If you use a Microsoft account, the change syncs to other Windows devices you own, but a local account changes only on that computer.

Step-by-step instructions for Settings

Press the Windows key and type "Settings", then open the Settings app. On the left side, click "Accounts". Click "Your info" at the top of the list on the left. You will see your current username displayed with a "Rename your account" button underneath it.

Click "Rename your account". A text box will appear with your current name highlighted. Delete it and type your new username. Windows usernames can contain letters, numbers, hyphens, and underscores, but not spaces or special characters like @, #, or $. Click "Next", then "Finish". Sign out of your account and sign back in to see the change take effect.

What happens to your files and programs

Your files stay exactly where they are. Windows keeps your Documents, Downloads, Desktop, and Pictures folders in the same location on your hard drive. Shortcuts and file paths that point to your user folder will update automatically — you do not have to move anything or fix broken links.

All your installed programs continue to work. Your passwords, browser bookmarks, email accounts, and settings remain unchanged. The only thing that changes is the name that appears on the sign-in screen and in the top-right corner of Windows.

Changing a username on a Microsoft account versus a local account

If you sign in with an email address (a Microsoft account), your username change syncs to any other Windows 10 or Windows 11 devices you own and sign into with the same email. This usually happens within a few hours. Your Microsoft account email address itself does not change — only the display name does.

If you sign in with a username that does not use an email (a local account), the change affects only that computer. Other devices on your network or other people using your network will not see the change. Local accounts are less common now, but they are still used on computers that are not connected to a Microsoft account.

If you cannot find the Rename button

On some older Windows 10 machines or computers managed by a workplace, the "Rename your account" button may not appear. This usually means your account is managed by your organization or your computer is set up in a way that restricts changes. Try right-clicking the Settings app and choosing "Run as administrator", then navigate back to Accounts > Your info.

If the button still does not appear, your computer administrator has disabled this feature. Contact your IT department or the person who manages your computer. They can change your username for you or give you permission to do it yourself.

Using the Control Panel method (older Windows versions)

If you are using an older version of Windows 10 or need an alternative route, you can change your username through the Control Panel. Press the Windows key and type "Control Panel", then open it. Click "User Accounts", then "User Accounts" again. Click "Change your account name" on the left side. Type your new username and click "Rename".

This method works the same way as the Settings method — your new name takes effect when you sign back in, and nothing else on your computer changes. The Settings app is faster if it is available on your version of Windows, but the Control Panel route works as a backup.

What you cannot change this way

Changing your username does not change your Microsoft account email address. If you want to change the email you use to sign in, you need to go to account.microsoft.com and change it there. That is a separate process and takes longer because Microsoft sends a verification email to confirm the change.

You also cannot change your username to one that is already in use on the same computer. If you have multiple user accounts on one device, each one must have a different name. Windows will tell you if the name you chose is already taken and ask you to pick a different one.

Frequently Asked Questions

Will changing my username log me out of everything?

No. Your passwords, email accounts, and app logins stay the same. You will need to sign out and sign back in to see the new username appear, but you will not be logged out of anything automatically. When you sign back in with your password, all your accounts and apps will still be connected.

Can I change my username back if I change my mind?

Yes. Follow the same steps and type your old username (or any new one you prefer). There is no limit to how many times you can change it. Windows does not track your old usernames or prevent you from reusing one.

Does changing my username affect my Wi-Fi or network passwords?

No. Your Wi-Fi password and any network credentials are stored separately from your username. You will stay connected to your networks after the change. If you are on a workplace network, your network login may be different from your Windows username, and changing one does not affect the other.

What if I share a computer with other people?

Each person has their own account with their own username, files, and settings. Changing your username does not affect anyone else's account. Other users will see your new name on the sign-in screen, but their own usernames and files remain untouched.

Can I use spaces or special characters in my new username?

No. Windows usernames can only contain letters, numbers, hyphens, and underscores. Spaces, periods, and special characters like @, #, $, or ! are not allowed. If you try to use them, Windows will show an error and ask you to choose a different name.
