How to Change Default User at Startup in Windows 10 and 11

Setting a different default user account at startup in Windows 10 or Windows 11 can streamline your login process, especially if multiple users share a device. Whether you want to automatically log into a specific account for convenience or set a different account as the default for certain tasks, this guide walks you through the steps to change the default user that Windows loads when you start your computer. Before proceeding, ensure you have administrator privileges, as making these changes requires administrative access. Additionally, consider whether you want to set up automatic login or simply change the default user that appears on the login screen.

What You’ll Need

• Administrator access to the Windows PC
• The username and password of the account you want to set as default
• Optional: Knowledge of how to access User Accounts and the Registry Editor

Step-by-Step

1. Log into Windows with an administrator account. Ensure you have admin rights to make system-wide changes.
2. Open the User Accounts settings. Press Win + R, type netplwiz, and press Enter. This opens the User Accounts window.
3. Select the user account you want to set as default. In the list of users, click on the account to highlight it.
4. Uncheck the box labeled ‘Users must enter a user name and password to use this computer.’ if you want automatic login for this account. If you want to change which account appears first at login, proceed to the next step.
5. Configure automatic login (optional): If you want Windows to log in automatically to your chosen account, click Apply, then enter the password when prompted. Confirm the password to enable auto-login.
6. Set the default user for Windows 10/11 to load at startup: To do this, you need to modify the registry. Type regedit in the Run dialog (Win + R) and press Enter.
7. Navigate to the registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI.
8. Backup the registry: Before making changes, right-click on the LogonUI key and select Export to save a backup.
9. Modify the default user: Locate the DefaultUserName DWORD or string value and set it to the username of your preferred account.
10. Set the default domain (if applicable): Change the DefaultDomainName value to your domain or computer name.
11. Close Registry Editor and restart your computer. The system should now log in with the selected default user, or load the account at the login screen if auto-login is configured.

Common Mistakes

• Editing the registry without backing it up can cause system issues. Always export a backup before making changes.
• Not having administrator rights can prevent you from making necessary changes.
• Using incorrect account names or domain names in the registry may result in login issues.
• Forgetting to enable auto-login after configuring registry settings can cause the default account not to load automatically.
• Overlooking password requirements when enabling auto-login can lead to login failures.

Tips

• Use the netplwiz method for a simple way to change the default user without editing the registry.
• To disable auto-login, revisit netplwiz and recheck the box for requiring user login.
• Ensure your user account has a password set if auto-login is enabled; otherwise, the process may not work as expected.
• For multiple users, consider creating separate user profiles for better privacy and organization.
• Always restart your PC after making changes to verify that the new default user is correctly set.

Troubleshooting

If your system does not automatically log in to the selected user or the default user does not appear as expected, try these steps:

• Revisit the netplwiz settings to ensure the correct user is selected and auto-login is enabled.
• Check the registry entries to confirm that DefaultUserName and DefaultDomainName are correctly set.
• Ensure you have entered the correct password during the auto-login setup.
• If you encounter login errors, try disabling auto-login, restart, and manually log in to check account functionality.
• Run Windows Update to ensure your system is up to date, as outdated software can cause login issues.
• Use the System Configuration tool (msconfig) to verify startup settings.

If problems persist, consider creating a new user account and setting it as default, or seek professional assistance.

Frequently Asked Questions

2. Will changing the default user affect other user accounts?

No, it only changes which account appears first or logs in automatically; other accounts and their data remain unaffected.

3. Is it safe to enable auto-login on my PC?

Enabling auto-login can pose security risks, especially on shared or public computers, as anyone can access your account without a password.

4. How do I revert to the original login screen after setting a default user?

Revisit netplwiz and recheck the box requiring user login, or disable auto-login in the registry and restart your computer.

5. Can I change the default user without editing the registry?

6. What should I do if the account I want isn’t listed in netplwiz?

Ensure the account exists and is active. You may need to create the user account first via Settings > Accounts > Family & other users.
