Windows NT includes a feature that allows you to automatically logon to the machine and network, bypassing the Winlogon dialog box.

To enable this function you need to add several new values to the [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon] key.

1. Add a new value of 'DefaultUserName' and set the data to the username you wish to automatically logon as.

2. Add a new value of 'DefaultPassword' and set this to the password for the username above.

3. Add a new value of 'DefaultDomainName' and set this to the domain of the user. Ignore this value if the NT box is not participating in NT Domain security.

4. Add a new value of 'AutoAdminLogon' and set it to either '1' to enable auto logon or '0' to disable.

5. Exit and reboot, Windows should not ask for a password and automatically show the desktop of the user.

WARNING: The password is stored in registry, which means anyone who has access to the machine has access to the password.

Note: You can bypass this function by holding the during the boot process.

Key: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]

Value Name: AutoAdminLogon

Data Type: REG_SZ

Data: (0=disable, 1=enable)
