Detect if PC is at Login screen (Ctrl+Alt+Del)

[NiVZ]

Hello,

We use AutoIt to write silent install/upgrade scripts for our organisation which are then sent to user's PC's (XP/2000) by software delivery.

The installs can take place during the day so we need to handle the following scenarios:

1. The PC is at the login screen (Ctrl+Alt+Del) - Silent Install

2. The PC is loggged in but the person is not using the application we are installing/upgrading - Popup at Start and Complete

3. The PC is logged in and the person is currently using the application we are installing/upgrading - Popup asking to close App and then at Complete

During the install I want to make it popup messages if someone is logged in (ie telling them to exit the application, or that the upgrade has finished and they can use the PC again) but if they are not logged in I want it to run completely silently.

I did try reading the @Username variable, but as the script is running via software delivery, using elevated permissions, the @Username is always SYSTEM and reading HKEY_CURRENT_USER reads the SYSTEM registry entry instead of the currently logged in users one.

Any help greatly appreciated.

You cannot detect when a computer is at the login screen because you script can't run in that state..

Try this:

Func IsLocked ()
    Return (WinGetProcess ("") > 999999)
EndFunc

From msdn

A service application conforms to the interface rules of the Service Control Manager (SCM). It can be started automatically at system boot, by a user through the Services control panel applet, or by an application that uses the service functions. Services can execute even when no user is logged on to the system.

Ok, i'll restate that:

You can't run an AutoIt script without loggin in without a service wrapper.

There are non-AI programs that can run other programs like AutoIt exe's as a (fake?) service.

Sorry I should have made it more clear. I compile the AutoIT script to a .exe and then send the compiled script to the remote PC using software delivery which allows me to run scripts while the remote PC is at the login screen.

While 1
    Sleep(1000)
    If _isWorksatationLocked() Then ConsoleWrite(@HOUR & ":" & @MIN & ":" & @SEC & " - " & "workstation locked" & @CRLF)
WEnd

Func _isWorksatationLocked()
    If StringInStr(WinGetText(""), "Program Manager") <> 0 And WinGetTitle("") = "" Then Return 1
    Return 0
EndFunc   ;==>_isWorksatationLocked

Thanks for the replies, but I think I've misled some of you - I don't want to check if the workstation is locked. I need to check if the PC is logged out completely (ie switched on and waiting to login or Shutdown -> logoff)

I'm going to try the WinGetTitle and check if the window title of the login box is there so thanks for pointing me in the right direction muttley

Did you ever find a solution to this?
