Note that the user name and password credential for auto login will be saved and stored in the Windows Registry, and can be read by anybody who can physically gain access to the computer, or remotely connect to the registry by the Authenticated Users group. Hackers or malicious users can also gain access to everything that is on the computer, including any network or networks that the computer is connected to. Thus, enable and turn on automatic logon on a domain environment will severely compromise the network security.

- Navigate to the following registry key:
- Double-click the DefaultUserName entry, type the user name to log on with, and then click OK.
If DefaultUserName registry value name is not found, create the new String Value (REG_SZ) with value name as DefaultUserName.
- Double-click the DefaultPassword entry, type the password for the user account under the value data box, and then click OK.
If there is no DefaultPassword value, create a new String Value subkey (REG_SZ) with DefaultPassword as the value name.Note that if no DefaultPassword string is specified, Windows automatically changes the value of the AutoAdminLogon registry key from 1 (true) to 0 (false) to turn off the AutoAdminLogon feature.

If the DefaultDomainName does not exist, create a new String Value (REG_SZ) registry key with value name as DefaultDomainName.

If there is no AutoAdminLogon entry, create a new String Value entry (REG_SZ) with AutoAdminLogon as the value name.
