How to log in to Windows User Account Automatically without any Password


A secured Windows login account with a password will require you to enter the password every time you want to login to your operating system.  If you use the computer alone, you can bypass the password entry at the system start without deleting the password. In this way, Windows can automatically log in a user on start up. To make this work you have to log in to a user account with administrator rights and open the Registry Editor. Then,

  • Click ‘Start > Run’, type ‘regedit.exe’ and confirm with ‘OK’.
  • In Vista and Windows 7, you can directly enter the command in the search field of the start menu.
  • Navigate to the left side of the tool to the ‘HKEY_LOCAL_MACHINE\SOTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon’ key.
  • Now you only need to change some values on the right side for activating the automatic log-in.
  • For this, double-click the entry and enter the new configuration in the ‘Edit String’ dialog box under ‘Value’.
  • Subsequently, confirm this action with ‘OK’.

Winlogon key to Windows automatically logs you in

If one of the values described in the following do not exist, create it.

  • Use the command ‘Edit > New > String’ for this and name it ‘AutoAdminLogon’.
  • Double click the ‘AutoAdminLogon’ and change the value to ‘1’ which basically turns on the automatic login.

If you subsequently wish to turn off the mechanism, replace the ‘1’ with a ‘0’. Enter the name of the user account that you wish to log in to, under ‘DefaultUserName’. If it’s not there create it. You also need to enter your password under ‘DefaultPassword’, which will also need to be created if it’s not visible. But keep in mind that your user account password will now be visible to everyone in the registration
database.

This is a security risk, if the computer is accessible to other persons, without supervision. If you need to log-in to a specific domain, enter it under ‘DefaultDomain Name’. Otherwise, you can do without this value. Close the Editor with ‘File > End’. From now on, you need not log in manually, Windows does this automatically. You can temporarily bypass this function by keeping system start [Shift] pressed.

NOTE: this automatic login works only if the users account you intend this for is protected by a password. Otherwise, this process fails.
