The Registry value entries that control the logon sequence for starting Windows NT are found under the following Registry key:   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

AutoAdminLogon  REG_SZ   0 or 1

Specifies automatic logon if this value is 1. You must also add the value entry DefaultPassword with a value for the user listed under DefaultUserName for automatic logon to work. When AutoAdminLogon is used, Windows NT automatically logs on the specified user when the system is started, bypassing the CTRL+ALT+DEL logon dialog box. CacheLastUpdate  REG_SZ

For internal WinLogon use only. <pre class="fixed_text">CachePrimaryDomain  REG_SZ   Domain name - Default: NEWDOMAIN <pre class="fixed_text">CacheValid  REG_SZ --- Default: 1 For internal WinLogon use only. <pre class="fixed_text">DebugServerCommand  REG_SZ   No or Yes --- Default: no For the internal Microsoft debug tool used to debug CSRSS.EXE <pre class="fixed_text">DefaultDomainName  REG_SZ   Domain name

Default: NEWDOMAIN Specifies the name of the last successfully logged on domain. <pre class="fixed_text">DefaultPassword  REG_SZ   Password --- Specifies the password for the user listed under DefaultUserName. Used during automatic logon. <pre class="fixed_text">DefaultUserName  REG_SZ   Username --- Specifies the name of the last successfully logged on user. If values are defined for DefaultPassword and AutoAdminLogon, this is the user who is logged on by default during automatic logon. <pre class="fixed_text">LegalNoticeCaption  REG_SZ   String

Default: (none) Specifies a caption for a message to appear when the user presses CTRL+ALT+DEL during logon. Add this value entry if you want to add a warning to be displayed when a user attempts to log on to a Windows NT system. You must acknowledge this message before proceeding with the logon. To specify text for the message, you must also specify a value for LegalNoticeText. <pre class="fixed_text">LegalNoticeText  REG_SZ   String - Default: (none) Specifies for a message to appear when the user presses CTRL+ALT+DEL during logon. Add this value entry if you want to add a warning to be displayed when a user attempts to log on to a Windows NT system. The user cannot procede with logging on without acknowledging this message. To include a caption for the logon notice, you must also specify a value for LegalNoticeCaption. <pre class="fixed_text">ReportBootOk  REG_SZ   0 or 1 -- Default: 1 When this value is set to 0, it disables the automatic (default) startup acceptance, which happens after the first successful logon. This value must be 0 if you use alternate settings in the BootVerification or BootVerificationProgram keys. <pre class="fixed_text">Shell  REG_SZ   Executable names - Default: taskman,progman,wowexec Specifies executables that are run by USERINIT and that are expected to be in the user's shell program. If for some reason WinLogon cannot start the entries listed in Userinit, then WinLogon will execute the entries in Shell directly. <pre class="fixed_text">System  REG_SZ   Executable names -- Default: LSASS.EXE,SPOOLSS.EXE Specifies executables to be run by WinLogon in the system context. These are activated during system initialization. <pre class="fixed_text">Userinit  REG_SZ   Executable names

Default: USERINIT,NDDEAGNT.EXE Specifies executables to be run by WinLogon when a user logs on. These executables are run in the user context. The first entry (USERINIT) is responsible for executing the shell program. NDDEAGNT.EXE is needed to run NetDDE.
