By default, the Windows XP Welcome Screen does not include the Administrator account in its account list. However, we can add the Administrator account to this list by following these steps:
1. Run the "Regedit" command to open the Registry Editor. Navigate to "[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]". In the right-hand window, find "LogonType" (if it doesn't exist, create a new one with the type REG_DWORD), and set its value to 1.
2. Next, navigate to "[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList]". Under this key, create a new item named "Administrator" and set its default value to 1.
For other accounts, you can also use a similar method to add them to the Welcome Screen account list. If you want to remove an account from the Welcome Screen list, simply delete the item named after the account under this registry branch or set its default value to 0. This approach can be beneficial for protecting your privacy.
