I tried the following, to create a user and allow auto logon (in Win XP SP3). The user is created. All three net commands returned :The command completed successfully. But the DefaultUserName is not changed. Any suggestions / corrections ? Thanks. Code: net user "My_User_Name" "" /add net localgroup Administrators "My_User_Name" /add net accounts /maxpwage:unlimited REGEDIT /S autologon.reg EXIT Code: Windows Registry Editor Version 5.1 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon] "DefaultUserName"="My_User_Name" "DefaultPassword"="" "AutoAdminLogon"="1" BTW, I did not use nLite. I integrated XP SP3, and used winnt.sif for the unattended install. Also, I ran the above cmd file after the unattended install.
