How to Create and Change Your Windows 10 Username 🖥️

Your Windows 10 username is the name that appears on your login screen and identifies your user account on your computer. Whether you're setting up Windows 10 for the first time or want to change an existing username, the process is straightforward—though the steps differ slightly depending on your account type and what you're trying to accomplish.

What Is a Windows 10 Username?

Your username is the account name associated with your Windows profile. It's separate from your password and serves as your identifier on the computer. When multiple people use the same device, each person has their own username and account, which keeps personal files, settings, and preferences separate.

Windows 10 supports different account types, and the type you use affects what you can and cannot do with your username.

Types of Windows 10 Accounts

Local Account A local account exists only on your individual computer. You create a username and password that work only on that device. This gives you full privacy on that machine but means your settings won't sync across other devices.

Microsoft Account A Microsoft account links your Windows profile to Microsoft's online services. Your username is typically an email address. This allows settings, files, and preferences to sync if you sign in on multiple devices using the same account.

The account type matters because changing or creating a username works differently for each.

How to Create a New User Account in Windows 10

If you need a separate account on your computer (for another family member, for example), here's the general path:

  1. Open Settings (press the Windows key + I, or search "Settings")
  2. Navigate to Accounts
  3. Select Family & other users (or Other users in some Windows versions)
  4. Click Add another person to this PC
  5. Choose whether to add a Microsoft account or a local account
  6. Follow the prompts to set the username and password

For a Microsoft account, you'll enter an existing email address or create a new one. For a local account, you'll type the username you want directly.

How to Change Your Username (Local Account)

If you have a local account and want to change your username, the process requires accessing Computer Management:

  1. Right-click the Start menu and select Computer Management
  2. Navigate to System Tools > Local Users and Groups > Users
  3. Right-click your username and select Rename
  4. Type the new username and press Enter
  5. Restart your computer to apply the change

After restart, your new username will appear on the login screen and in file explorer.

Changing Your Display Name (Microsoft Account)

If you use a Microsoft account (usually identified by an email address), you have a distinction:

  • Your login username (email) typically cannot be changed through Windows settings
  • Your display name (what appears on the lock screen and Start menu) can be changed:
  1. Go to Settings > Accounts > Your info
  2. Click Manage your Microsoft account or Manage your account settings online
  3. Update your display name through your Microsoft account portal
  4. Sign out and back in to see the change reflected in Windows

Important Variables That Affect Your Options đź”§

FactorWhat It MeansHow It Matters
Account TypeLocal or Microsoft accountDetermines which method you use to change your username
Administrator PrivilegesWhether your account has admin rightsYou need admin access to rename a local account
Sign-In MethodPassword, PIN, biometric, or Windows HelloDoesn't affect username changes, but you'll still need your current credentials
Active Files & PermissionsFiles and settings linked to the old usernameSome file paths may show the old username even after renaming

Common Questions

Will changing my username affect my files? Not directly. Your personal files stored in the user folder remain accessible. However, the folder path itself may still show the old username depending on how Windows handles the transition. This rarely causes problems for most users.

Can I change my login email if I use a Microsoft account? Your Microsoft account email address (your login username) can be changed, but this typically happens through your Microsoft account settings online, not directly in Windows. The process varies based on your account setup.

Do I need a password to change my username? For local accounts, you'll need administrator credentials. If you forgot your password, you'll need to reset it first through your account settings or recovery options.

What if I'm the only user on this computer? You can still change your username following the steps above. The process is the same whether you're a solo user or one of many.

Best Practices When Creating or Changing Usernames

  • Keep it simple: Avoid special characters or spaces that might cause confusion
  • Make it recognizable: Use names that you or other household members will remember
  • Plan ahead: If multiple people will use this computer, establish a naming system
  • Note your account type: Remember whether you're using a local account or Microsoft account—it affects future sign-in options
  • Backup before major changes: If you're changing usernames on a heavily used account, it's wise to back up important files first

What You Should Know Before Making Changes

Changing a username is generally safe and reversible—you can change it again if you prefer something different. However, some applications or file permissions might still reference your old username, though this rarely causes practical problems on a home computer.

The most important variable is understanding your own account type and whether you're trying to change your actual login username or just your display name. These are different processes with different limitations depending on whether you're using a local or Microsoft account.
