On Windows 8 I don't have the option on a PC I am dealing with to auto login.
In netplwiz I don't have the checkbox, as screenshotted:

Any suggestions?

Windows 8 is fairly smart, if you do not have the option - then you are most likely on a domain (i.e. a work computer that has policies set for computers on the domain by a central authority trying to encourage security).
Otherwise you are in the right spot, and since the image does not show the necessary checkbox - my bet is you are on a domain.
Take a look at Microsoft's page on that.
An untested workaround
I am not about to test this on my work domain nor would I suggest this, but for the intel piece, do the following as an admin.
regeditHKLM\Software\Microsoft\Windows NT\CurrentVersion\winlogon Set the value for AutoAdminLogon = 1 (1 = auto, 0 = off)DefaultPassword, in the value field enter your password.DefaultUserName (type: REG_SZ), make that the user you want logged in by default.domain, you may need to add a string for DefaultDomainName with the value of the domain you are on.Again, this is untested. I take no responsibility for you breaking your computer messing around in the registry or angering an IT manager for having an auto-logon setup.
I would discourage it since you really shouldn't need to logout and in that often and it isn't too hard to type out a password for those occasions. That being said, if you try it and it does/doesn't work - please report back for future peoples.
command line:
REG ADD "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v AutoAdminLogon /t REG_SZ /d 1
REG ADD "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultUserName /t REG_SZ /d %USERNAME%
REG ADD "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultPassword /t REG_SZ /d <Your password>
Domain, if need:
REG ADD "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultDomainName /t REG_SZ /d %USERDNSDOMAIN%
REG ADD "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\UserSwitch" /v Enabled /t REG_DWORD /d 1 /f

I always use AutoLogon from Sysinternals.
With this way that data are encrypted.
