How do I change automatic logon via Script or Command Line?

Question

After deploying a Windows 7 image to Stand alone machines we run into the following problem.

If we set autologon to off then we have to log in manually and activate Windows and Office - the Keys are installed but the products are not activated. (These laptops are set as loan laptops so may not be used for months after they are imaged - grace period expired)

If we do set Autologon to on and run a script to activate the products on first logon - when they are network connected, then the machine will always log on to the account we have specified in the autologon.

I was wondering, is there a way to turn off autologon via a script?
It can be done manually by following the instructions in this post or via a registry key(HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\AutoAdminLogon)

I'm not sure how to manage this from the command line or a script if anyone could point me in the right direction it would be much appreicated.

One can change the registry via a .reg file.

For example, create an autologin.reg file containing :

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
"AutoAdminLogon"="1"
"DefaultUserName"="Administrator"
"DefaultPassword"="Pa$$w0rd"

Add DefaultDomainName if required, then just execute the file to get the values into the registry.

Or in a cmd script :

REG ADD "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon" /v AutoAdminLogon /t REG_SZ /d 1 /f
REG ADD "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultDomainName /t REG_SZ /d domainname /f
REG ADD "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultUserName /t REG_SZ /d Administrator /f
REG ADD "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefaultPassword /t REG_SZ /d Pa$$w0rd /f

_{(Warning: I didn't test the above.)}

Just execute it from a bat file? – Joe Taylor Sep 30 '11 at 10:10
Yes for the 2nd one, run as administrator. – harrymc Sep 30 '11 at 10:17
Calling a reg file from a bat file to run at first logon worked for me. – Joe Taylor Oct 04 '11 at 10:17
The data type for AutoAdminLogon should be REG_SZ and not REG_BINARY. – Irukandji Jul 24 '12 at 11:57
@baijiu: Well, I did warn that it was untested... Fixed now. – harrymc Jul 24 '12 at 13:16
Be sure to run the x64 reg.exe on x64 Windows. (`set proc` will display `PROCESSOR_ARCHITECTURE=x86` in a WoW64 `cmd.exe`. In that case you'll need to run `%SystemRoot%\SysNative\reg.exe`.) – Kevin Smyth Mar 25 '14 at 20:35

Can't you just use sysprep /oobe? It will finalize your install and show the welcome screen on reboot.

Read what sysprep is and how sysprep works for more information.

I use sysprep /oobe to prepare the image, we then deploy the image using WDS. When we do this with machines we join to the domain we never have this problem but when the machine is a stand alone machine it keeps the auto logon for some reason. – Joe Taylor Sep 30 '11 at 22:18
@JoeTaylor: That's generalization. What I meant was to run `sysprep /oobe` *after* deployment, so it'll leave the audit mode which WDS has put it in. This should get rid of the auto login settings, which are only intended to be present during the audit... – Tamara Wijsman Sep 30 '11 at 22:21
Will you still be able to specify the OOBE arguments - region, usernames, etc? – Joe Taylor Oct 01 '11 at 10:59
@JoeTaylor: Sorry, I don't know what you mean by that. I have seen the thing I describe as working, but don't know about customizing what you describe. I think region is configured as part of the unattended installation (it was like that when I used MDT, I don't know how to do this by command), the users can be added using something like `net user /?`. – Tamara Wijsman Oct 01 '11 at 16:57

Sysinternal's Autologon should be able to auto logon only once. That was a function when I've used it a while ago but I'm not seeing any details on whether it does that now.

I was hoping for something native to Windows 7 but thanks for the advice. – Joe Taylor Sep 30 '11 at 22:20
Does Autologon have command line options that I'm unaware of? – Tamara Wijsman Sep 30 '11 at 22:24
@JoeTaylor: It takes a simple `net start webclient && copy \\live.sysinternals.com\Tools\Autologon.exe .` to obtain it if you have an internet connection... :) – Tamara Wijsman Sep 30 '11 at 22:24
