AutoAdminLogon

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

Data type	Range	Default value
REG_SZ	0 | 1	0

Description

Determines whether the automatic logon feature is enabled. Automatic logon uses the domain, user name, and password stored in the registry to log users on to the computer when the system starts. The Log On to Windows dialog box is not displayed.

Value	Meaning
0	Disables automatic logon.
1	Enables automatic logon.

Activation method

You must log off of Windows 2000, shut down the computer, and start it again before changes to this entry take effect.

Note

Automatic logon requires that the DefaultDomainName and DefaultUserName entries appear in the registry with valid values.

Caution

Automatic logon allows other users to start your computer and to log on using your account.

Because automatic logon proceeds in a different order than an authenticated logon, it can cause timing conflicts. If you are loading several network transport protocols, automatic logon might cause Windows 2000 to attempt to connect to network resources before the protocols' network transports are completely loaded.

If you disable automatic logon by setting the value of AutoAdminLogon to 0, delete the value of DefaultPassword, which is stored and displayed in the registry editor in plain, unencrypted text.
