Send Ctrl-Alt-Del and Enter, via script

Hello. I am looking for a way to Ctrl-Alt-Del and Enter, via script.

REASON: We have a few computers running apps (telephone system logging, etc) that we need to log in after a reboot. I have configured the registry to auto logon, but my problem is that there is a group policy that displays a popup message at logon, which requires an Enter/click OK button.

To get around this, I was thinking that I could create a modified reboot script, that waits 10-15 minutes after the reboot, and then sends a Ctrl-Alt-Del and Enter. That shoudl do the trick for the login, I just dont know how to accomplish it via Kaseya scripting.

Thanks in advance.

Lloyd

How about creating and AutoIt3 script? It will run from the command line and will allow you to send keystrokes to a computer. You can also do cool things like move the mouse around and use mouse clicks. I have never tried it for this purpose, but I don't see a reason why it wouldn't work.

ericpeterson,

Thanks very much for your suggestion. I had heard of AutoIt3, but never used it.

I downloaded it, installed it, and began to play and research this morning. I found my way to the Help File, and found myself in the Function Send section. I was so excited, until I saw the sentence "Windows does not allow the simulation of the "CTRL-ALT-DEL" combination."

So, it looks like AutoIt3 will not work, and possibly nothing would either. Rats.

Thanks anyway. I appreciate the recommendation.

Not sure if this will help, but you can control the use of CAD and the Logon Legal Notice via the registry at:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

Settings:
DisableCAD - Set to 0 for False, 1 for True
LegalNoticeCaption - String of Text or set to empty string to disable
LegalNoticeText - String of Text or set to empty string to disable

Gred,

Thanks for the reply. In our case, we do want/need the Ctrl-Alt-Del to logon, as well as the Legal Notice on the computers.

So, I am tryign to find a way to script pressing Ctrl-Alt-Del and clickign okay - so that I could fire the script - on these special machines, if I found that no user is logged in.

Sounded simple to me at first, but it is turnign out to be near impossible.

Download tweakUI and configure the autologon setting to log yourself on, then set the screen saver to kick off with a password after 1 minute to lock the computer.

Wouldn't the easier answer be to remove this/these computers from the specific group policy? Whilst its the least technical, it does solve a lot of effort Smile

Windows might not allow for a software program to invoke this key combo, but it's certainly possible to send it by faking a keyboard. VNC does this (right click the VNC window in the taskbar and click "send Ctrl+Alt+Del"). VBScript allows for the sending of "^%{DELETE}" which sends Ctrl+Alt+Del (see here: http://www.devguru.com/Technologies/wsh/quickref/wshshell_SendKeys.html)... Not sure if that suits your purposes. It certainly sounds like a fun project to make work.

For that systems and block the policy that shows the pop up.

I'm trying to find a way to do this to..

The VBscript method doesn't work.

Also tried a one liner in AutoIT but it doesn't work either: Send("^!{DELETE}")

I want to run some spyware removal tools overnight, but they pop up with windows, so I doubt they can run without someone being logged in. Love to find a solution to this.

Cheers,
Daniel

I wonder how VNC gets around this... something to do with it running as a service maybe?

I don't understand why you don't just disable the logon message GPO for these computers and use the AutoLogon feature to automatically log a user on to these systems.

Because I don't want the PC to auto-logon any time except for when I am running scripts at night. During the day, the client should have to enter their domain logon/password.

This is great! It actually works! Except...

After logging in, the script (calling logon.exe) reports success.. but the desktop never shows. Also "CTRL+ALT+DEL" doesn't do anything.

I thought, no worries, I'll just run another script to run explorer.exe - this works, and I can run any other script. But I can't log off. I also notice an application in the task manager (by right clicking the clock, I can't use CTRL+ALT+DEL) which I can't kill.

Any ideas? Do you experience the same behaviour?

It doesn't seem too bad of a side-effect, but some dialog boxes I can hear the beep, but it never shows on screen.

Thanks,
Daniel
