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:

enter image description here

Any suggestions?

Please fix your screenshot – Pretzel Jul 26 '13 at 13:55

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.

  1. Ctrl+R and type regedit
  2. Navigate (on the left) to HKLM\Software\Microsoft\Windows NT\CurrentVersion\winlogon Set the value for AutoAdminLogon = 1 (1 = auto, 0 = off)
  3. Create a string value called DefaultPassword, in the value field enter your password.
  4. Look for/create a value for DefaultUserName (type: REG_SZ), make that the user you want logged in by default.
  5. If you are on a 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.

Well in this case the domain is my own domain used for the microsoft login nonsense. Why should this prevent it? – Marcus Hughes Jul 26 '13 at 14:04
@MarcusHughes - Updated. Looks like STTR also has the fast way of adding keys for you. – nerdwaller Jul 26 '13 at 14:20
No luck, neither (same things) worked – Marcus Hughes Jul 26 '13 at 14:37
@MarcusHughes - This is the right answer to your question. You asked why the check-box was missing, and the reason is because you've joined a domain. If your question is actually "How do I enable auto-logon when the box is missing", then that's a different question, one which may have answers here (amongst other places): Does Windows 7 allow auto-login with a stored password, like TweakUI did? – Ƭᴇcʜιᴇ007 Jul 26 '13 at 15:37
It's not the correct answer as I am certain I am not on a domain – Marcus Hughes Jul 26 '13 at 16:13

I always use AutoLogon from Sysinternals.

With this way that data are encrypted.

I also tried this, no luck – Marcus Hughes Jul 26 '13 at 18:27
You must run it with admin rights:… – magicandre1981 Jul 27 '13 at 5:33
No, this didn't work. I just retested – Marcus Hughes Jul 27 '13 at 12:10
I use this tool for years and it works. Do you use a local or MS account? – magicandre1981 Jul 27 '13 at 18:36
It was a Microsoft account, I tried converting it yesterday to see if it would work but still no luck. I understand it may work for you but it doesn't here and that's why I am asking for assistance?... – Marcus Hughes Jul 27 '13 at 23:04

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%

This did not have any effect – Marcus Hughes Jul 26 '13 at 14:39
@MarcusHughes REG ADD "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\UserSwitc‌​h" /v Enabled /t REG_DWORD /d 1 /f – STTR Jul 26 '13 at 17:47
