The fastest way: use Control Panel

Open Control Panel, go to User Accounts, select your account, and click "Change your name" at the top left. Type the new name you want, click "Rename" and restart your computer. That's the complete process — Windows 7 makes this straightforward because the username and the display name are separate things, and you're changing the display name that appears on the login screen and in menus.

The display name is what other people see when you share files or send messages on a network. Changing it does not affect your password, your files, or any programs you have installed. Everything stays exactly where it was.

Key Takeaways

  • You change your display name through Control Panel > User Accounts, not by editing system files or using the command line.
  • The change takes effect after you restart your computer, and you do not need to log out and back in — a full restart is required.
  • Your password, files, and installed programs remain unchanged; only the name shown on the login screen and in Windows menus changes.
  • If you cannot find User Accounts in Control Panel, switch the view from Category to Classic Icons using the link on the left side.

Step-by-step walkthrough

Step 1: Click the Start button in the bottom left corner. Type "Control Panel" into the search box and press Enter. The Control Panel window opens.

Step 2: Look for "User Accounts" in the list. If you see it, click it. If Control Panel is showing large icons and you do not see User Accounts, click "Switch to Classic View" on the left side, then look again.

Step 3: Click on your account name (the one you are currently logged into). A new window appears with options for your account. At the top left, you will see a link that says "Change your name". Click it.

Step 4: A small dialog box appears with a text field containing your current name. Delete the old name and type the new one. Click "Rename" when you are done.

Step 5: Restart your computer. The new name appears on the login screen and in the Start menu after the restart completes.

Why the restart is necessary

Windows 7 stores your display name in multiple places — the login screen, the Start menu, user profile folders, and the registry. A restart ensures all of these locations update at the same time. If you do not restart, some parts of Windows may still show the old name until you do.

You do not need to log out and back in; a full shutdown and restart is what makes the change stick everywhere.

What does not change when you rename your account

Your password stays the same. You still log in with the same password you used before. Your files remain in the same folders. Your Documents, Desktop, Downloads, and all other user folders keep their contents and their locations.

Programs you have installed continue to work. Your email accounts, browser bookmarks, and saved settings do not change. Windows is only changing the label on your account, not the account itself.

If you cannot see the "Change your name" option

You may not have permission to change your own account name if you are logged in as a standard user rather than an administrator. Ask whoever set up the computer to log in with their administrator account, open User Accounts, and change the name from there.

Alternatively, if you are the administrator and the option is still missing, restart your computer in Safe Mode and try again. Safe Mode sometimes clears temporary glitches that prevent the option from appearing.

Changing the account name versus the computer name

Your account name is the username that appears on the login screen and in the Start menu. Your computer name is the name Windows uses to identify your machine on a network — it appears in Network settings and when you share files with others.

The steps above change only your account name. If you also want to change your computer name, that is a separate process done through System settings, not User Accounts. Most people only need to change the account name.

Frequently Asked Questions

Do I need to change my password after changing my username?

No. Your password remains the same. You log in with the same password you used before the name change. The username and password are separate — changing one does not affect the other.

Will changing my username affect my email or online accounts?

No. Your Windows username is only used on your computer. Your email address, social media accounts, and other online logins are completely separate and do not change when you rename your Windows account.

What if I change my mind and want to change the name back?

Follow the same steps again. Open Control Panel > User Accounts, click your account, select "Change your name", type the old name (or any new name), click Rename, and restart. You can change your account name as many times as you want.

Can I change someone else's account name on the same computer?

Only if you are logged in as an administrator. Open Control Panel > User Accounts, click the account you want to change (not your own), select "Change the account name", type the new name, and restart. The other person will see the new name when they log in next.

Does renaming my account affect shared files or network access?

Not for most purposes. If you share files with others on your network, they can still access them after you rename your account. However, if you have set up very specific network permissions based on your old username, those may need to be updated manually — ask your network administrator if you are unsure.
