Windows NT - Registry Editing Tips

Automatically Log On a User when NT Boots

For NT 3.51:
Use REGEDT32.EXE, and search for the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon. Fill in the keys DefaultDomainName, DefaultUserName, and DefaultPassword with the values of the already-established Windows NT user. You may have to add the DefaultPassword key.
Then choose Add Value from the menu and add a new key, named AutoAdminLogon. Select REG_SZ for the Data Type. Enter "1" (without the quotes) in the String field.
Save the changes and restart - Windows NT should automatically log the system on as that user.

For NT 4.0:
The Method above does not work properly with NT 4.0. The easiest method is to simply download the Microsoft TWEAKUI powertoy. It has a tab labeled "NETWORK" that allows you to specify what user id and password you want NT 4.0 to automatically use for logging on during the boot process.
NOTE: This can be a BIG security problem - only use it on machines that are physically secured.
