The quickest way to change your username

Open the Control Panel, go to User Accounts, select your account, and click "Change your account name" — that is the entire process. Windows 8.1 stores your username separately from your password, so changing one does not affect the other. The change takes effect when ready, though you may need to sign out and back in to see it everywhere on your computer.

The steps below walk you through each screen. If you are the only person who uses this computer, you can do this yourself. If multiple people have accounts on the machine, only the account owner or someone with administrator rights can make the change.

Key Takeaways

  • Your Windows 8.1 username is separate from your password, so changing your name does not log you out or reset your security.
  • You must have administrator rights to change any account name, including your own.
  • The change appears when ready in most places, but you may need to sign out and back in to see it in all applications.
  • Changing your username does not affect your files, folders, or installed programs — they stay exactly where they are.

Step 1: Open Control Panel and find User Accounts

Press the Windows key and type "Control Panel" without quotes. Click the Control Panel icon when it appears. In the window that opens, look for "User Accounts" — it may say "User Accounts and Family Safety" depending on your view. Click it.

If you see a list of categories instead of icons, look for the blue link that says "User Accounts" on the left side of the window. Click that instead. The exact wording depends on whether you are in Icon View or Category View, but both lead to the same place.

Step 2: Select your account from the list

You will see a list of all user accounts on the computer. Find your own account — it will have your current username next to your profile picture. Click on it once.

If you only see one account and it is not labeled with a name you recognize, that is still your account. Windows sometimes displays it as "Administrator" or "Guest" depending on the account type. The account with the checkmark next to it is the one you are currently signed into.

Step 3: Click "Change your account name"

After you click your account, a new window opens with several options. Look for the blue link that says "Change your account name" — it is usually near the top of the list. Click it.

Do not click "Change your password" or "Change account type" — those do different things. You want only the "Change your account name" link. If you do not see this link at all, scroll down in the window to see if it appears below the visible area.

Step 4: Type your new name and confirm

A small dialog box appears with a text field containing your current username. Delete the old name and type the new one. Windows 8.1 allows usernames up to 20 characters and does not allow certain symbols like asterisks, question marks, or forward slashes.

Click the "Rename" button. The window closes and you are done. Your new username takes effect when ready on the sign-in screen and in most applications. If you see your old name somewhere after restarting, sign out completely and sign back in — that usually clears it.

What happens to your files and programs

Your files, folders, and installed programs do not move or change when you rename your account. Everything stays in the same place. If you had shortcuts on your desktop or in your Start menu, they continue to work exactly as they did before.

Some older programs may still show your old username in their settings or in file paths, but they will continue to run normally. You do not need to reinstall anything or move any files around. The folder where Windows stores your personal files (usually C:\Users\YourName) keeps the old folder name, but your account still has full access to it.

If you cannot find the "Change your account name" option

This usually means you do not have administrator rights on this account. If you are the computer owner, you can give yourself those rights by going back to User Accounts, clicking your account, and looking for "Change account type" — set it to "Administrator" instead of "Standard User".

If someone else set up the computer and you do not have their password, you will need to ask them to make the change for you. They can do it from their own administrator account by following the same steps and selecting your account instead of their own. Administrator rights are required because changing account names affects system-level settings.

Frequently Asked Questions

Will changing my username log me out?

No. Your username and password are separate. Changing your name does not affect your password or your sign-in status. You stay logged in the whole time and can continue working when ready after the change.

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

Yes. Follow the same steps and type your old username in the text field. Windows allows you to change it as many times as you want with no restrictions or waiting period.

What if I see my old username in Windows Explorer or in a program?

Sign out completely (not just lock the screen) and sign back in. That usually refreshes the display everywhere. If it still shows the old name in one specific program, that program may be storing the name in its own settings — check that program's preferences or settings menu.

Does changing my username affect my Microsoft account?

No. Your Windows 8.1 username and your Microsoft account email are two different things. Changing one does not change the other. Your Microsoft account continues to work the same way.

What characters can I use in my new username?

Windows 8.1 allows letters, numbers, spaces, and most punctuation except asterisks, question marks, forward slashes, and backslashes. Usernames are limited to 20 characters total. Avoid using only numbers or spaces, as Windows may reject those.
