The quickest way: Settings on Windows 10 and 11

Open Settings by pressing the Windows key and typing "Settings", then select the app. Go to Accounts in the left sidebar, then click Your info at the top. You will see your current username under your profile picture. Click the blue Rename your account button, type your new username, then click Next and Finish. The change takes effect when ready, though you may need to sign out and back in to see it everywhere.

This method works on any Windows 10 or 11 machine where you have admin rights. If you do not see a Rename button, your account is managed by your workplace or school — contact your IT department, because they control the change.

The new username appears on your sign-in screen, in File Explorer, and in Settings. Any files you already own stay yours; Windows straightforward updates the folder path from C:\Users\OldName to C:\Users\NewName.

Key Takeaways

  • Settings > Accounts > Your info > Rename your account is the standard path on Windows 10 and 11, and the change takes effect after you sign out and back in.
  • Your username and your Microsoft account email are separate — changing one does not change the other.
  • If you see no Rename button, your account is managed by an organization and you will need to contact your IT support team.
  • Changing your username does not affect your files, installed programs, or saved passwords — Windows updates the folder path automatically.

What happens to your files and programs

Windows moves your user folder from C:\Users\OldName to C:\Users\NewName automatically. Your Documents, Desktop, Downloads, and Pictures folders all move with it. Any program shortcuts on your desktop stay in place, and your installed programs continue to work.

Passwords saved in your browser and in Windows Credential Manager stay with your account. Some programs that store settings in your user folder may need to be restarted to recognize the new path, but this is rare and usually happens without you noticing.

If you cannot see the Rename button

Your account may be a managed account — one controlled by your employer, school, or organization. Managed accounts do not allow username changes through Settings. Contact your IT department or help desk and ask them to change your username. They have the tools to do it safely on their end.

If you are the only person who uses this computer and you set it up yourself, but still see no Rename button, restart your computer and try again. Sometimes Settings needs a refresh to show the option.

Changing your Microsoft account email versus your username

Your Windows username and your Microsoft account email are two separate things. Changing your username in Settings does not change the email you use to sign in. If you want to change your sign-in email, go to Settings > Accounts > Your info and look for Manage your Microsoft account. That link takes you to Microsoft's website, where you can change your email address.

If you sign in with a local account (not a Microsoft account), you have only a username, not an email. The Rename button in Settings is the only way to change it.

What to do if you forgot your username

Open Settings and go to Accounts > Your info. Your username appears under your profile picture. If you are locked out of Settings, restart your computer and look at the sign-in screen — your username is shown there as well.

If you cannot remember your password, you can still see your username on the sign-in screen. Click I forgot my password to reset it using a recovery email or phone number.

Changing username on older Windows versions

On Windows 7 or earlier, the process is different. Go to Control Panel > User Accounts > Manage another account, select your account, then click Change the account name. Type your new name and click Rename. Windows 8 uses a similar path through Control Panel, though the exact wording varies slightly.

If you are still using Windows 7, Microsoft stopped supporting it in January 2020. Consider upgrading to Windows 10 or 11 for security updates and new features.

Frequently Asked Questions

Will changing my username log me out?

You will remain signed in when ready after the change, but you may see a brief delay before the new username appears everywhere. Signing out and back in ensures all programs and folders recognize the new name right away.

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

Yes. Go back to Settings > Accounts > Your info and click Rename your account again. Type your old username and click Finish. There is no limit to how many times you can change it.

What if I have multiple user accounts on one computer?

Each account has its own username and can be changed independently. Sign in to the account you want to rename, then follow the Settings steps above. Other accounts on the computer are not affected.

Does changing my username affect my WiFi or network password?

No. Your network passwords are stored separately from your username. You will not need to re-enter WiFi passwords or reconnect to networks after a username change.

Can I use special characters or spaces in my new username?

Windows allows letters, numbers, and most punctuation in usernames, but some characters like asterisks or question marks are not permitted. Spaces are allowed but can cause problems with some programs, so avoid them if possible.
