Several months ago, and several months before that, we ran a tip
describing a Registry edit that allows automatic log-on. We continue
to get many requests for a way to automate log-on. So, here is the
June edition of the tip.
For this tip to work, you must have a password, and you must enter the
password that you chose for your system log-on. If you enter a
different password, you'll have problems with other programs.
Keep in mind the usual warnings about making changes to the Registry.
Run RegEdit and navigate to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Winlogon
Look in the right pane for AutoAdminLogon. If it's there, double-click
it and change the value to 1.
If it isn't there, choose Edit, New, String Value. Name the new value
AutoAdminLogon. Now double-click the new entry's icon and give it the
value 1. Click OK.
For the automatic log-on to work, you have to add your password. Look
for DefaultPassword in the right pane. If it isn't there, create it by
choosing Edit, New, String Value. Double-click the new icon and when
the dialog box opens, assign your password to it. Click OK to close
the dialog box. (Note: The password cannot be a space or a null
string. If you use a space or null string, this tip will not work).
Now you can close RegEdit and restart the computer.     


Start without logon under Windows 95, 98
On a home PC isn't logon operation absolutely necessary. It's easy to get rid of . Start the Registry Editor (regedit.exe) and locate the following key: 
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer 

Create the new entry NoLogOff  as Binary Value and set it to the following value: 01 00 00 00 
 Close the Registry Editor, and reboot to make the change take effect.
