Vista Auto Logon

According to: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=829701&SiteID=1 If you have a single user without password, then he gets logged on automatically after restart.
Not recommended! Of course, anyone with sufficient access to read your registry, can read your password in plain text if you set it up this way…

Here’s the procedure:
Open Regedit,

• Drill down to HKLM/Software/Microsoft/Windows NT/CurrentVersion/Winlogon,
• Find the “AutoAdminLogon” value, and change it to 1. Enter the following items as new string values: “DefaultUserName”, and “DefaultPassword”.
• Set the value of DefaultUserName to be the username that you want to autologin, and set the value of DefaultPassword to be that user’s password.
