Auto Logon Workaround for Windows 7 64 Bit Machine
1) Create DefaultDomainName, DefaultUserName and DefaultPassword strings in the registry HKLM\Software\Microsoft\Windows NT\Current version\Winlogon and set the appropriate values.
2) Set the value for AutoAdminLogon string in HKLM\Software\Microsoft\Windows NT\Current version\Winlogon to 1.
