Yes, you can change your Windows username, and it takes about five minutes
You can change the name that appears on your Windows login screen and in system settings without losing any files, programs, or settings. The process is straightforward and works the same way on Windows 10 and Windows 11. You do not need to reinstall anything or create a new account — your existing account straightforward gets a new name.
The method you use depends on what kind of account you have. If you log in with a Microsoft account (the email address you use for Outlook, OneDrive, or Xbox), you change the name through Microsoft's website. If you use a local account (a username and password stored only on your computer), you change it directly in Windows Settings.
Key Takeaways
- Changing your username does not affect your files, programs, or any data stored on your computer.
- Microsoft account users change their display name on the Microsoft account website, while local account users change it in Windows Settings.
- The change takes effect the next time you restart your computer or log out and back in.
- Your old username folder on the hard drive stays the same, but Windows displays your new name everywhere else.
Changing a Microsoft account username
If you log in with an email address, you have a Microsoft account. Go to account.microsoft.com and sign in with that email and password. Click your name or profile picture in the top right corner, then select View account or Manage your Microsoft account.
Look for a section called Your info or Personal info. You should see a field labeled Name or Display name. Click Edit name or the pencil icon next to it. Type your new name in the boxes provided — usually a first name field and a last name field. Click Save or Next. The change appears on your Windows login screen and in Settings the next time you restart your computer.
Changing a local account username
If you log in with just a username (not an email address), you have a local account. Open Settings by pressing the Windows key and typing settings, then press Enter. Click Accounts on the left side of the window.
Select Your info at the top of the list. You should see your current username displayed. Click the Rename your account button or link. Type your new username in the box that appears and click Next, then Finish. Restart your computer or sign out and back in to see the change take effect.
What stays the same after you change your username
Your files, documents, photos, and downloads all remain exactly where they are. Programs you have installed continue to work without any changes. Your passwords, saved Wi-Fi networks, and browser history do not move or disappear. Windows keeps all your settings, preferences, and customizations intact.
The folder on your hard drive that holds your personal files keeps its old name. If your old username was "Sarah" and you change it to "Sarah Chen", the folder might still be called "C:\Users\Sarah" on the back end, but Windows displays "Sarah Chen" everywhere you see it in the interface. This does not cause any problems — it is how Windows handles the change behind the scenes.
If you cannot find the rename option
On some computers, especially those set up by a workplace or school, the rename option may be hidden or disabled. If you do not see Rename your account in Settings, your account may be managed by an administrator. Contact your IT department or the person who set up your computer.
If you are using a Microsoft account and the name field on the Microsoft website appears grayed out or locked, your account may have restrictions set by your organization. You can still try changing it through Windows Settings: open Settings, go to Accounts, click Your info, and look for Edit name or a pencil icon. Some computers allow the change in Settings even when the Microsoft website does not.
Changing your username versus creating a new account
Renaming your existing account is different from creating a brand new account. When you rename, you keep everything — all your files stay in place, all your programs remain installed, and all your settings stay the same. When you create a new account, you start fresh with an empty desktop and no programs or files.
You should rename your account if you straightforward want a different name but want to keep everything else. You should create a new account if you want a completely separate space on the same computer, such as one account for work and one for personal use. If you are trying to fix a problem with your account or remove access for someone else, creating a new account is usually the better choice.
Frequently Asked Questions
Will changing my username log me out of programs or websites?
No. Your saved passwords, login information, and browser sessions remain active. You will not need to sign back into email, social media, or any other services. The change only affects what name appears in Windows — it does not touch your online accounts or stored credentials.
Can I change my username back if I do not like the new one?
Yes. Follow the same steps you used to change it the first time. You can rename your account as many times as you want. There is no limit to how many times you can make the change.
What if I share my computer with other people?
Each person who logs in has their own account with their own username, files, and settings. Changing your username does not affect anyone else's account. Other users will still see their own usernames when they log in, and their files remain separate from yours.
Does changing my username affect my Microsoft account or email?
No. Your email address and Microsoft account stay exactly the same. Changing your Windows username only changes the display name on your computer. Your email, OneDrive, Xbox account, and all other Microsoft services continue to work without any changes.
What if I forgot my password and need to change my username?
You need to log in before you can change your username. If you forgot your password, reset it first. For a Microsoft account, go to account.microsoft.com and click Can't access your account. For a local account, use the password reset disk or recovery options on your login screen, or contact your administrator.
