The fastest way to change your user name
Open Settings by pressing the Windows key and typing "settings", then select the Settings app. Go to Accounts in the left menu, then click Your info at the top. You will see your current user name displayed under your profile picture. Click the Rename your account button, type your new name, click Next, then Finish. The change takes effect when ready, and you do not need to restart your computer.
This method changes only the display name — the friendly name that appears on the sign-in screen and in the Start menu. It does not change your actual account name (the folder name in C:\Users\). For most people, this is all you need.
Key Takeaways
- The display name change through Settings takes 30 seconds and requires no restart.
- Your user folder in C:\Users\ keeps its original name even after you change the display name, which prevents problems with programs that reference that folder.
- If you need to change the actual account folder name, you must use a local administrator account and rename the folder manually, which carries more risk.
- Changing your user name does not affect your files, installed programs, or passwords — everything stays in the same place.
What changes and what stays the same
When you rename your account through Settings, Windows changes the name that appears on your sign-in screen, your Start menu, and anywhere else your profile is displayed to other people using the same computer. Your files remain exactly where they are. Programs you have installed continue to work. Your passwords do not change. Any shortcuts or favorites you have saved stay intact.
The one thing that does not change is the folder name inside C:\Users\. If your old account name was "Sarah" and you rename it to "Sarah Chen", your files still live in C:\Users\Sarah\, not C:\Users\Sarah Chen\. This is actually a good thing — many programs store settings and data by looking for that folder path, and changing it can break those programs. Windows keeps the folder name the same to prevent that problem.
When you might need to change the actual folder name
Most people never need to do this. But if your original account name was something you no longer want to see anywhere — including in file paths and error messages — you can rename the folder itself. This is more complicated and requires you to be logged in as a different administrator account.
To rename the folder, log out of the account you want to rename and log in as a different administrator account. Open File Explorer and navigate to C:\Users\. Right-click the folder with the old account name, select Rename, type the new name, and press Enter. Windows will ask for confirmation. After you rename it, log back into the renamed account. The account will still work, but the folder path has changed, so check any programs that reference file locations to make sure they still point to the right place.
This method carries more risk because if something goes wrong during the rename, you could lose access to your files. Only do this if you are comfortable troubleshooting, or if the display name change is not enough for your situation.
Changing the name on a Microsoft account versus a local account
If you sign in with a Microsoft account (an email address and password you use across multiple devices), changing your user name in Windows Settings changes only how it appears on that specific computer. Your Microsoft account name itself — the email address — does not change. If you want to change your actual Microsoft account name, you have to do that through the Microsoft account website, not through Windows.
If you sign in with a local account (a name and password that exists only on that computer), the Settings method changes your display name on that computer only. There is no separate account name to change elsewhere.
Troubleshooting if the rename button does not appear
If you do not see the Rename your account button in Settings, you are probably signed in as a standard user rather than an administrator. Standard users cannot change their own account name. Ask whoever set up the computer to change it for you, or switch to an administrator account if you have access to one.
If you are signed in as an administrator and the button still does not appear, try restarting your computer and checking Settings again. If the problem continues, your account may be linked to a work or school organization that restricts changes. Contact your IT department or the person who manages your account.
What happens to your files and programs after you rename
Nothing breaks. Your Documents, Downloads, Desktop, and Pictures folders all stay in the same place with all your files inside them. Programs you have installed continue to run normally. Shortcuts on your desktop and Start menu continue to work. Email accounts, browser bookmarks, and saved passwords all remain exactly as they were.
The only time you might see a problem is if you have a program that was specifically designed to look for a user folder with your old name in the file path. This is rare, but if it happens, the program will straightforward not find what it is looking for. You can usually fix this by reinstalling the program or updating its settings to point to the correct location.
Changing the name for other people who use your computer
If you are an administrator on the computer, you can change another person's account name the same way. Go to Settings, then Accounts, then Other people. Click the account you want to rename, then click Rename account. You do not need their password to do this. The next time they sign in, they will see the new name on the sign-in screen.
If you want to rename a child's account that you manage through Family settings, the process is the same — go to Other people and select their account.
Frequently Asked Questions
Will changing my user name affect my password?
No. Your password stays the same. You will still sign in with the same password you used before. The name change is separate from your login credentials.
Can I change my user name back to what it was before?
Yes. Follow the same steps through Settings and type your old name. There is no limit to how many times you can change it. You can change it back whenever you want.
What if I forgot my password and need to change my user name?
You cannot change your user name without signing in first. If you have forgotten your password, you will need to reset it before you can access Settings. Use the sign-in screen to reset your password, then follow the steps above to change your name.
Does changing my user name on Windows 10 change it on other devices?
Only if you use a Microsoft account and you change your account name through the Microsoft website. Changing it in Windows Settings changes only that computer. If you use a local account, the change affects only that computer.
Can I use special characters or spaces in my new user name?
Yes. Windows allows spaces, numbers, and most punctuation in display names. The display name can be almost anything you want. The actual folder name (if you ever need to change it) has more restrictions and cannot contain certain characters like asterisks or question marks.
