37. How to avoid password entry at start up ?

Open Administrative tools in control panel and go to Local security policy.Select accounts and within that password policies. Set minimum password length to 0. This should be enough to stop password from being entered at startup.I have received some criticism for asking users to set their password length to 0 and I agree to some of the potential security risks. Here is one better way to do it.
Go to START-RUN and enter "control userpasswords2" select the user the you would like to have auto logon set to and then uncheck "Users must enter a user name and password to use this computer". Ok out. Now you have to do one more thing. Go to START-RUN and enter "control userpasswords" and clicking on “Change the way users log on or off”, and unchecking both “Use the Welcome Screen” and “Use Fast User Switching”.
There is another way to get to the same screen. Try this to auto logon 1. At a command prompt, type: rundll32 netplwiz.dll,UsersRunDll 2. In the User Accounts dialog that appears, clear the "Users must enter a user name and password to use this computer" check box and click OK. 3. Enter the user name and password of the account you want to automatically log on.
Now Reboot and see it happen.
