The fastest way to see your username

Your Windows 10 username appears in the bottom left corner of your lock screen, right above the password field. When you turn on your computer or wake it from sleep, look at the name displayed there — that is your username. If you are already logged in, you can also find it by clicking the Start button, then your profile picture in the top left of the menu. The name shown is your Windows username.

If neither of those locations shows a name you recognize, or if you need to confirm which account you are actually using, the Settings app will show you the exact username your system recognizes. This matters because sometimes the display name (what appears on the lock screen) differs from the actual username (what the system uses behind the scenes).

Key Takeaways

  • Your username appears on the Windows 10 lock screen above the password field, visible before you log in.
  • The Start menu profile picture also displays your username when you click it after logging in.
  • Settings > Accounts > Your info shows your official account name and lets you see which type of account you have.
  • If you see a display name that differs from your username, Settings will clarify which one the system uses for file permissions and network access.

Checking your username through Settings

Open Settings by pressing the Windows key and typing "settings", then press Enter. Once Settings opens, click Accounts in the left sidebar. Then click Your info at the top of the list. The page that appears shows your account name at the very top, along with your account type (Microsoft account or Local account).

This view shows you the name Windows uses internally for your account. If you have a Microsoft account, you may see an email address here instead of a traditional username. If you have a local account, you will see the username you created when you set up Windows. Both are correct — they are just different account types.

Finding your username in File Explorer

Open File Explorer by pressing the Windows key and E together. In the left sidebar, look for This PC. Click on it, then look at the address bar at the top. You will see a path that looks like "This PC" followed by folders. Click on the home icon (the folder with a house on it) in the toolbar, and the address bar will show a path containing your username.

The path typically reads something like "C:\Users\YourUsername". The part after "Users\" is your actual Windows username. This method works even if you are not sure what you saw on the lock screen, because it shows you the folder name Windows created for your account.

What to do if you see multiple usernames

Some computers have more than one user account. If you see different names in different places, you may be looking at different accounts. The username that matters is the one you are currently logged into — that is the one shown on the lock screen when you first turn on the computer, or the one shown in Settings under Your info.

If you need to know the usernames of other accounts on the computer, you can find them by going to Settings > Accounts > Other people. This shows all user accounts on the machine, though you will need administrator permission to see full details or make changes to other accounts.

Understanding local accounts versus Microsoft accounts

Windows 10 lets you sign in with either a local account (a username and password stored only on your computer) or a Microsoft account (which uses an email address and connects to Microsoft services). Your username works differently depending on which type you have.

With a local account, your username is whatever you typed when you created the account. With a Microsoft account, your username is typically your email address, though Windows may display a shortened version on the lock screen. To see which type you have, go to Settings > Accounts > Your info and look for the line that says "Account type". It will say either "Microsoft account" or "Local account".

Checking your username from the command line

If you prefer using the command line, you can see your username when ready. Press the Windows key and type "cmd", then press Enter to open Command Prompt. Type echo %username% and press Enter. The system will print your username on the next line.

This method shows you the exact username Windows uses for file paths and system permissions. It is the fastest way if you are comfortable with Command Prompt, and it works the same way on every Windows 10 computer.

Frequently Asked Questions

Is my username the same as my display name?

Not always. Your display name is what appears on the lock screen and in the Start menu. Your username is what Windows uses internally for file folders and permissions. In Settings > Your info, you can see both. If they are different, the username is the one that matters for system functions.

Can I change my Windows 10 username?

Yes, but the process depends on your account type. For a Microsoft account, you change your display name in Settings > Accounts > Your info by clicking "Manage your Microsoft account online". For a local account, you can change the display name the same way, but the actual folder name stays the same.

What if I forgot my username and can't see the lock screen?

If you are already logged in, open Settings > Accounts > Your info to see your account name. If you cannot log in at all, restart the computer and look at the lock screen before entering your password — your username will be displayed there.

Why do I see an email address instead of a username?

You are using a Microsoft account. Microsoft accounts use email addresses as usernames. This is normal and works the same way as a traditional username for all Windows functions. You can see your account type in Settings > Accounts > Your info.
