The two ways to change your administrator username

You can change your administrator username through Settings (the easier route for most people) or through Computer Management (the faster route if you know what you're doing). Both methods work on Windows 10 Home and Pro. You do not need to restart your computer after making the change, though some programs may not recognize the new name until you log out and back in.

Before you start, make sure you are logged in as the administrator account you want to rename. If you are logged in as a standard user, you will not see the option to change the administrator account name.

Key Takeaways

  • Open Settings, go to Accounts, then select your account name and choose "Rename your account" to change it in about 30 seconds.
  • The change takes effect when ready, but some programs and cloud services may still show the old name until you restart your computer.
  • Changing the username does not change your password, and you will still log in the same way you always have.
  • If you cannot find the rename option in Settings, use Computer Management instead by right-clicking "This PC" and selecting "Manage".
  • The folder name on your hard drive (C:\Users\[oldname]) does not change automatically, which can cause problems with some programs.

Changing your username through Settings (the fastest method)

Open Settings by pressing the Windows key and typing "settings", then press Enter. Click on "Accounts" in the left sidebar. On the right side, you will see your current account name at the top. Click on it.

A window will open with your account details. Look for the button that says "Rename your account" and click it. Type your new username in the box that appears. Windows will ask you to confirm the change. Click "Next", then "Finish". Your new username is now active.

The change appears when ready in Settings, the Start menu, and the lock screen. However, if you have cloud services connected to this account (OneDrive, Outlook, Microsoft 365), those services may continue showing your old name until you sign out and sign back in.

Changing your username through Computer Management (if Settings does not work)

Right-click on "This PC" or "My Computer" on your desktop or in File Explorer. Select "Manage" from the menu. Computer Management will open. On the left side, click the arrow next to "Local Users and Groups" to expand it, then click on "Users".

You will see a list of all user accounts on your computer. Right-click on the administrator account you want to rename and select "Rename". Type your new username and press Enter. The change takes effect when ready.

Computer Management is more direct than Settings, but it does not show you a confirmation screen. If you make a typo, you will need to right-click and rename again to fix it.

What changes and what does not change

Your login password stays the same. You will still log in using the same password you always have — changing the username does not touch your password at all. Your Microsoft account (if you use one) is not affected. You can still sign in with your email address and password.

Your user folder on the hard drive does not change automatically. Windows stores your files in C:\Users\[username]. When you rename your account, Windows does not rename this folder. Some programs look for files in the old folder path and may not find them. If you use programs that store settings in your user folder (many older programs do), they may reset to default settings after you rename your account.

If this becomes a problem, you can manually rename the folder, but this requires careful steps and can break things if done wrong. Most people do not need to do this — it only matters if a program stops working after the rename.

Why you might want to change your administrator username

Some people change their username for privacy reasons — a generic name like "Admin" or "User1" is less identifying than a full name if someone else uses your computer. Others change it because they inherited a computer with a previous owner's name, or because they set up the account with a temporary name and want something permanent now.

Changing the username does not improve security on its own. Your password is what keeps your account safe, not the username. However, if your username is something very obvious (like "Administrator" or your full name), changing it to something less predictable is a small additional barrier against someone trying to guess their way in.

What to do if you cannot rename the account

If the "Rename your account" button does not appear in Settings, you may not be logged in as an administrator. Log out, log in to the administrator account, and try again. If you are already logged in as administrator and the button still does not appear, try Computer Management instead — it works on all Windows 10 versions.

If Computer Management also does not show your account, or if you get an error message when you try to rename, your account may be a Microsoft account rather than a local account. Microsoft accounts have restrictions on renaming through Windows itself. In that case, you can change your display name (the name that shows on the lock screen and Start menu) by going to Settings > Accounts > Your info and clicking "Manage your Microsoft account", but the underlying account name cannot be changed without creating a new local account.

The folder name problem and when it matters

After you rename your account, your files are still in C:\Users\[oldname]. Windows does not move them. This usually does not cause problems — Windows knows where to find your files. However, some programs have hardcoded paths that look for files in a specific user folder. If a program was installed when your username was "Sarah" and you rename it to "SarahM", that program might still look in C:\Users\Sarah and fail to find what it needs.

You can check if this is happening by opening File Explorer, clicking on "This PC", then "C:", then "Users". You will see your old folder name still there. If a program stops working after you rename your account, this folder is usually the culprit. You can rename the folder itself to match your new username, but this is a manual process that can cause problems if done incorrectly. Most people find it easier to just reinstall the problematic program.

Frequently Asked Questions

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

No. The change takes effect when ready in Windows. However, some programs may not recognize the new name until you restart, and cloud services like OneDrive may continue showing the old name until you sign out and back in. If a program seems confused about your username, restarting usually fixes it.

Can I change my username if I use a Microsoft account to log in?

You can change your display name (what shows on your lock screen and Start menu) through Settings > Accounts > Your info, but the underlying account name is tied to your Microsoft email and cannot be changed without creating a new local account. If you need a completely different username, you would need to set up a new local account instead.

What happens to my files and programs when I change my username?

Your files stay where they are. Programs continue to work in most cases. However, some older programs may not find their settings files if they were looking in the old user folder path. Reinstalling the program usually fixes this. Your installed programs themselves do not need to be reinstalled.

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

Yes. Use the same method you used to change it the first time — either through Settings or Computer Management. You can rename your account as many times as you want. There is no limit on how many times you can change it.

Does changing my username affect my password?

No. Your password stays exactly the same. You will log in with the same password you always have. Changing the username is completely separate from your password.
