The quickest way to change your Dell username
On a Dell computer running Windows, you change your username through Settings, not through the Dell system itself. Dell computers use the same Windows account system as any other PC, so the process is identical whether your Dell is a desktop, laptop, or workstation.
The fastest route depends on whether you use a Microsoft account (the one you log in with online) or a local account (stored only on your computer). Most Dell computers sold in the last five years use a Microsoft account by default. If you are not sure which you have, look at your login screen — if you see an email address, it is a Microsoft account. If you see just a name, it is likely a local account.
Changing either type takes about five minutes and requires you to be logged in as an administrator. You will not lose any files, programs, or settings — only the name that appears on your login screen and in Windows menus changes.
Key Takeaways
- Microsoft account usernames are changed through your Microsoft account online, while local account usernames are changed directly in Windows Settings on your computer.
- You must be logged in as an administrator to change your username on a Dell or any Windows computer.
- Changing your username does not affect your files, programs, or any data stored on your computer.
- If you forget your password or cannot log in, you will need to use a password reset disk or another administrator account to make changes.
How to change a Microsoft account username
If you log into your Dell with an email address, you have a Microsoft account. To change the name that appears on your computer, you log into your Microsoft account online and update your profile name there. The change appears on your Dell the next time you restart.
Go to account.microsoft.com in any web browser and sign in with your email and password. Click "Your info" on the left side. Under your profile picture, you will see your current name. Click "Edit name" and type the new name you want to use. Click "Next" and then "Finish". Restart your Dell computer, and the new name will appear on your login screen and in the Start menu.
The email address you use to log in stays the same — only the display name changes. This means you can still sign into your computer with the same password, and any Microsoft services linked to that account (OneDrive, Outlook, Xbox) will still work.
How to change a local account username
If you log into your Dell with just a name (not an email), you have a local account. Local accounts are stored only on your computer, so you change the username directly in Windows Settings.
Open Settings by pressing the Windows key and typing "Settings", then press Enter. Click "Accounts" on the left side. Click "Your info" at the top. You will see your current username displayed. Click "Rename your account" and type the new name you want. Click "Next" and then "Finish". You do not need to restart — the change takes effect when ready.
Your files and programs remain untouched. The only thing that changes is the name displayed on your login screen and in Windows menus. If you have other local accounts on your Dell, their names and settings stay exactly as they were.
What happens to your files and folders after you change your username
When you change a local account username, Windows does not automatically rename your user folder (the folder that holds your Documents, Downloads, Desktop, and other personal files). Your files stay in the old folder path, which can sometimes cause confusion, but everything still works normally.
For example, if your old username was "Sarah" and you change it to "Sarah Chen", your files are still in C:\Users\Sarah\. Windows knows to look there, so you will not notice any difference. Programs that save files to your Documents folder will still save them to the right place.
If you want to rename the user folder itself (which is optional and more advanced), you will need to use File Explorer and administrator permissions. Most people do not need to do this — the automatic behavior works fine. If you do want to rename the folder, create a backup of your files first, then right-click the folder, select "Rename", and type the new name.
Changing your username if you forgot your password
If you cannot log into your Dell because you forgot your password, you cannot change your username from the Settings menu. You have two options: reset your password first, or use another administrator account on the computer.
If you have a Microsoft account, go to account.microsoft.com on another computer or phone and click "Can't access your account?" Follow the steps to reset your password using a recovery email or phone number. Once you reset it, you can log back into your Dell and change your username normally.
If you have a local account and no other administrator account on your Dell, you will need a password reset disk (if you created one before) or you will need to contact Dell support or a local computer repair shop. Windows does not have a built-in way to reset a local account password without one of these.
Why you might want to change your username
People change their usernames for different reasons. You might want a more professional name if you use your Dell for work, or you might want to remove a name you no longer use. Some people change their username when they get married, start a business, or straightforward prefer a different name.
Changing your username is also useful if you inherited a Dell from someone else or bought a used one. Rather than keeping the old owner's name on your login screen, you can change it to your own name in a few minutes.
The change is cosmetic — it does not affect security, performance, or how your programs work. Your password stays the same (unless you change it separately), and all your files remain accessible.
Troubleshooting username changes on Dell computers
If you changed your username but it still shows the old name on your login screen, try restarting your computer. For Microsoft accounts, the change can take a few minutes to sync. For local accounts, the change should be when ready, but a restart ensures Windows has fully updated all the places where your username appears.
If you changed a Microsoft account name and it still shows the old name after restarting, sign out of your Dell completely, then sign back in. This forces Windows to refresh your account information from Microsoft's servers.
If you cannot find the "Rename your account" button in Settings, you might not be logged in as an administrator. Ask whoever set up your Dell to give you administrator permissions, or log in with a different account that has admin rights.
Frequently Asked Questions
Can I change my username without restarting my computer?
For local accounts, yes — the change takes effect when ready. For Microsoft accounts, you do not need to restart, but the new name may not appear everywhere until you do. Restarting ensures the change shows up on your login screen and in all Windows menus.
Will changing my username affect my Wi-Fi password or internet connection?
No. Your username is separate from your network settings. Your Wi-Fi password and internet connection will work exactly as before. The only thing that changes is the name displayed in Windows.
Can I change my username back to what it was before?
Yes, you can change it as many times as you want. Just follow the same steps and type your old name (or any new name) whenever you want to change it again.
What is the difference between changing my username and changing my password?
Your username is the name that appears on your login screen and in Windows menus. Your password is what you type to log in. You can change either one independently. Changing your username does not change your password, and vice versa.
Do I need to uninstall and reinstall my programs after changing my username?
No. Your programs will continue to work normally. They do not depend on your username. Files you created in those programs will still open, and your settings will stay the same.
