The Two Ways to Change Your Username
Windows 11 Pro gives you two separate paths to change your username, and which one you use depends on how your account is set up. The first method changes the display name — what appears on your login screen and in the Start menu — through Settings. The second method changes the actual account folder name on your hard drive, which is more involved and requires a second administrator account to do it safely.
Most people only need the first method. Your display name is what everyone sees, and changing it takes about two minutes. The folder name matters only if you're moving files, setting up backups, or troubleshooting permissions problems. If you're unsure which one you need, start with the display name change — you can always do the folder name later.
Key Takeaways
- Changing your display name through Settings is the quickest method and takes effect when ready on your login screen and Start menu.
- You must be logged in as an administrator to change your username through Settings.
- Changing your account folder name requires a second administrator account and involves renaming the folder in File Explorer, which can break permissions if done wrong.
- If you only have one administrator account, you can create a temporary second one, use it to rename your folder, then delete it afterward.
- Your Microsoft account email address stays the same no matter which method you use — only the display name changes.
Changing Your Display Name Through Settings
Open Settings by pressing Windows key + I on your keyboard. On the left side, click Accounts, then click Your info at the top of the list. You'll see your current username displayed under your profile picture.
Click the Rename button next to your username. A text box will appear with your current name highlighted. Delete the old name and type your new username, then click Next. Windows will ask you to confirm — click Finish to save the change. You'll see a message saying "Your name has been changed." The new name appears when ready on your lock screen and Start menu the next time you sign out and back in, though it often shows up right away without signing out.
This method only changes what's displayed — your Microsoft account email, your files, and your permissions all stay exactly the same. If you share your computer with other people, they'll see your new name on the login screen, but nothing about their accounts changes.
Changing Your Account Folder Name
Your account folder lives at C:\Users\[YourUsername] and contains all your documents, downloads, desktop files, and settings. Renaming this folder is more complex because Windows locks it while you're logged in, and changing it incorrectly can break file permissions. You'll need a second administrator account to do this safely.
If you have a second administrator account already, log into it. If you don't, you'll need to create one first. Go to Settings, click Accounts, then Other users, then Add account. Choose I don't have this person's sign-in information, then Add a user without a Microsoft account. Give it a temporary name like "Temp Admin" and a straightforward password you'll remember. After creating it, go back to Other users, click the new account, then click Change account type and select Administrator.
Log out of your main account and log into the temporary administrator account. Open File Explorer and navigate to C:\Users. Right-click the folder with your old username, select Rename, and type your new username. Press Enter. Windows may ask for administrator permission — click Yes. The folder will rename when ready.
Log back into your main account. Everything will work normally, but your account folder now has your new name. If you created a temporary administrator account, log back into it and delete it through Settings > Accounts > Other users. Your main account keeps all its files and permissions.
What Changes and What Stays the Same
Your Microsoft account email address does not change — it's tied to your account, not your username. If you sign in with an email address, that email stays your sign-in method. Your files, installed programs, and settings all stay in place. Your user profile picture, desktop background, and all your customizations remain exactly as they were.
Shortcuts and file paths that pointed to your old username may break if you only renamed the folder without updating them. Windows usually fixes these automatically, but if you have batch files, scheduled tasks, or network shortcuts that reference your old path, you may need to update them manually. This is rare for most home users, but it's worth checking if you use your computer for work or run automated tasks.
Troubleshooting a Failed Rename
If you try to rename your folder and get an error saying "The file is in use" or "Access denied," it means Windows is still using the folder. Make sure you're logged into a different administrator account — you cannot rename your own active account folder. If you're already in a different account and still get the error, restart your computer and try again.
If the rename succeeded but your account won't log in, or you see permission errors on your files, restart in Safe Mode and try renaming the folder back to its original name. Safe Mode loads fewer services and may let you undo the change. Press Windows key + R, type msconfig, click the Boot tab, check Safe boot, then restart. After you're back to normal, try the rename again more carefully, or contact Microsoft support if the problem persists.
When to Use Each Method
Use the Settings display name change if you straightforward want a different name on your login screen and Start menu. This is the right choice for 99 percent of people and takes two minutes with zero risk. Use the folder name change only if you're moving your account to a new computer, setting up automated backups that reference your username, or troubleshooting permission issues that require the folder name to match your username exactly.
If you're not sure whether you need the folder name changed, you probably don't. The display name is what matters for day-to-day use. The folder name is a technical detail that only shows up in File Explorer and command-line tools. Change it only if you have a specific reason to do so.
Frequently Asked Questions
Will changing my username log me out?
Changing your display name through Settings does not log you out — the change takes effect when ready or on your next sign-in. If you rename your account folder, you must be logged into a different account, so you'll need to sign out of your main account first. After the rename is complete, you can log back in with your new username and everything works normally.
Can I change my username if I'm not an administrator?
No. You must have administrator permissions to change your username through Settings or to rename your account folder. If you don't have administrator access, contact whoever set up your computer and ask them to give you administrator rights, or ask them to make the change for you.
What happens to my files if I change my username?
If you only change your display name through Settings, your files don't move and nothing changes. If you rename your account folder, your files stay in the new folder path and Windows updates the permissions automatically in most cases. Your files remain yours and you can access them normally after the rename.
Can I change my username back to the old one?
Yes. Follow the same steps to change it back — either through Settings for the display name, or by renaming the folder again if you changed the folder name. There's no limit to how many times you can change it.
Do I need to change my password when I change my username?
No. Your password is separate from your username and doesn't change when you rename your account. You'll still sign in with the same password you used before.
