By default Windows XP uses a welcome screen with a list of active accounts for the users to login, unless login process has been altered. There may become a time that you wish for certain accounts not to show on the welcome screen. You can do this by following the below steps.
NOTE: An account that does not show on the welcome screen does not mean the account is disabled or deleted. The account is just simply hidden visually.
- Start the Registry Editor (Start Menu -> Run -> type without quotes “regedit” and press enter).
- Go to HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon \ SpecialAccounts \ UserList \.
- Right-click an empty space in the right pane and select New > DWORD Value.
- Name the new value exactly as the account profile name not the user name of the account.
- Leave the Value data as 0 (zero).
- Close the registry editor.
If you want to enable this user again on the Welcome Screen, either double-click the account value, and change the Value data to 1, or delete the record.
