The fastest way to change your username

Open Settings, go to Accounts, select Your info, and click the "Rename your PC" button. Type your new username and restart your computer. Windows will update your account name across all your files, email, and programs in the background.

This method works whether you use a Microsoft account or a local account. The process takes about five minutes, and you do not need to reinstall anything or create a new user profile.

If you cannot find the Rename button, or if you see an error message, the alternative method in the next section will work instead.

Key Takeaways

  • The Settings app is the standard way to rename your account, and it preserves all your files, programs, and settings in their current location.
  • Your username and your computer name are separate things — changing one does not automatically change the other, though you can change both at once.
  • If Settings does not show a Rename button, you can change your username through the Control Panel or by creating a new local account and transferring your files.
  • After you restart, Windows may take several minutes to update your username in all programs and file locations — this is normal and does not require action from you.

Changing your username through Settings

Click the Windows Start button, type "Settings," and open the Settings app. Select "Accounts" from the left menu, then click "Your info" at the top of the right panel.

Look for a button labeled "Rename your PC" or "Rename your account." Click it, type your new username in the text box, and click "Next." Windows will ask you to restart your computer — click "Restart now" or "Restart later" depending on whether you have unsaved work open.

When your computer restarts, Windows updates your username in the system files. This usually takes a few minutes after you log back in. You may see your old username briefly in some programs or file locations — this is normal and clears itself within an hour.

What to do if the Rename button does not appear

Some versions of Windows 10 do not show the Rename button in Settings, particularly on older installations or computers managed by a workplace. In this case, use the Control Panel instead.

Click the Windows Start button, type "Control Panel," and open it. Select "User Accounts," then click "User Accounts" again in the next window. Click "Change your account name" on the left side, type your new username, and click "Rename." Restart your computer when prompted.

If you do not see a "Change your account name" option, your account may be managed by your workplace or school. Contact your IT department or system administrator — they control which settings you can change.

Changing your computer name at the same time

Your computer name is different from your username. The computer name appears on your network and in system settings; the username is what appears on your login screen and in file paths. You can change both, but they are separate steps.

To change your computer name, open Settings, select "System," then click "About" at the bottom of the left menu. Click "Rename this PC," type your new computer name, and restart. Windows will update the computer name on your network and in system settings.

Changing the computer name does not affect your files or programs. It only changes how your computer identifies itself to other computers and devices on your network.

Moving files if you want a completely fresh start

If you want to keep your old username's files separate from your new username, you can create a new local account with your desired name and move your files manually. This takes longer but gives you a clean break between the old and new username.

Open Settings, go to Accounts, and click "Other people" on the left. Click "Add account," select "I do not have this person's sign-in information," then "Add a user without a Microsoft account." Type your new username and a password, then click "Next."

Log out of your old account and log into the new one. Open File Explorer, navigate to C:\Users\, and copy the Desktop, Documents, Downloads, and Pictures folders from your old username's folder to your new one. Once you confirm all your files are in the new account, you can delete the old account through Settings > Accounts > Other people.

Why your username might not change when ready everywhere

After you restart, Windows updates your username in most places within a few minutes. However, some programs store your username in their own settings and do not check the system username automatically. Email clients, cloud storage apps, and older programs may still show your old username until you restart them or update their settings manually.

If a program shows your old username, close it completely and open it again. Most programs will detect the change on restart. If a program still shows the old name, check its settings or preferences for a username field and update it there.

Your file path — the location shown in File Explorer — updates automatically. You do not need to move or recopy any files.

Frequently Asked Questions

Will changing my username delete my files or programs?

No. Your files, programs, and settings stay exactly where they are. Windows updates the username in the system files and file paths, but nothing is deleted or moved. You can access everything the same way after the restart.

Can I change my username without restarting?

Windows requires a restart to fully update your username across all system files and programs. You can type the new name without restarting, but the change does not take effect until you restart your computer.

What if I use a Microsoft account instead of a local account?

The Settings method works the same way. Click "Rename your PC" in Settings > Accounts > Your info, type your new name, and restart. Your Microsoft account email address stays the same — only your Windows username changes.

Can I change my username back to the old one?

Yes. Follow the same steps through Settings or Control Panel and type your old username. Windows treats it as a new change and updates everything after a restart, just like the first time.

Why does my file path still show my old username?

File paths sometimes update slowly, especially if programs are still running. Close all programs and restart your computer. If the old path still appears in File Explorer after a full restart, the change is still processing — wait a few more minutes and refresh the view by pressing F5.
