The quickest way to change your username on Windows 8
Open the Settings charm by pressing Windows key + I, then select "Change PC settings" at the bottom. Go to "Accounts" and click "Your account" on the left. You'll see your current username at the top — click "Rename your account" and type the new name you want. Windows will ask you to confirm; click "Next" and then "Finish". The change takes effect the next time you sign in.
This method works whether you use a local account (one stored only on your computer) or a Microsoft account (linked to your email). The steps are identical either way. Your files, programs, and settings stay exactly where they are — only the display name changes.
Key Takeaways
- You can rename your account through Settings in under two minutes without restarting your computer.
- The change appears the next time you sign in, not when ready.
- Your user folder on the hard drive keeps its original name — only the account display name changes.
- If you forget your password, you cannot change your username from the Settings menu; you'll need to use a password reset disk or another administrator account.
- Renaming a Microsoft account through Windows 8 settings changes only the local display name, not your email address or Microsoft account itself.
What actually changes when you rename your account
Windows 8 distinguishes between your account name (what appears on the sign-in screen and in Settings) and your user folder (the directory where your Documents, Downloads, and Desktop live). When you rename through Settings, only the account name changes. Your user folder stays named after your original username.
This matters if you're looking at your hard drive in File Explorer. You'll still see a folder called "C:\Users\OldUsername" even though your account now displays as "NewUsername" everywhere else in Windows. This is intentional — changing the folder name can break programs and file shortcuts. Leave it alone.
If you use a Microsoft account instead of a local account
A Microsoft account is tied to an email address (usually @outlook.com, @hotmail.com, or another email you registered with Microsoft). When you rename your account in Windows 8 Settings, you're changing only the display name that appears on your computer — not your actual Microsoft account or email address.
If you want to change your Microsoft email address itself, you need to go to account.microsoft.com in a web browser, sign in, and change it there. That's a separate process from renaming your Windows account. The two names can be different, which confuses some people, but Windows allows it.
When the Settings method doesn't work
If you're signed in with an account that doesn't have administrator rights, the "Rename your account" option will be grayed out. You'll need to sign in as an administrator (someone who set up the computer or was given admin status) to change any account name.
If you've forgotten your password and cannot sign in at all, you cannot rename the account from within Windows. You would need to use a password reset disk (if you created one before forgetting the password) or sign in as a different administrator account and rename it from there through Settings.
Using the Control Panel method as an alternative
Windows 8 Settings is the faster route, but you can also rename your account through the Control Panel if you prefer. Press Windows key + X and select "Control Panel". Go to "User Accounts and Family Safety" and then "User Accounts". Click "Change your account name" and type the new name.
This method reaches the same result as the Settings charm — it's just older and requires more clicks. Most people find the Settings route faster, but if you're more comfortable with the Control Panel layout, either works.
What to do if you want to change your password instead
Renaming your account and changing your password are two separate things. If you want to change the password you use to sign in (rather than the name that appears), go to Settings > Accounts > Sign-in options and look for "Password". Click "Change" and follow the prompts. You'll need to enter your current password first.
For a Microsoft account, you can also change your password at account.microsoft.com. Changes made there will sync to your Windows 8 sign-in the next time you restart.
Frequently Asked Questions
Will changing my username affect my programs or files?
No. Your programs will continue to run, and all your files stay in the same place. Only the name displayed on the sign-in screen and in Settings changes. Some older programs that hardcoded your username into their settings might behave oddly, but this is rare.
Can I change my username without signing out?
Yes. You can rename your account while you're signed in. The new name takes effect when you sign out and sign back in, not when ready.
What if I change my mind and want the old name back?
Go back through Settings > Accounts > Your account > Rename your account and type your old name. Windows treats it as a new rename, so you can switch back and forth as many times as you want.
Does renaming my Windows 8 account change my Microsoft account email?
No. Your Microsoft account email stays the same. If you want to change your email address, you need to sign into account.microsoft.com separately. The Windows account display name and your Microsoft email are two different things.
Can I have two accounts with the same name?
No. Windows requires each account name on the computer to be unique. If you try to rename an account to a name that already exists, Windows will reject it and ask you to choose a different name.
