GUI compiled application will not shown when started as "Scheduled task" with SYSTEM account

[Tralveller]

Hello at all,

 

I try to start a compiled GUI application during an installation that runs as local "SYSTEM" account.

On normal use it works and the GUI comes up.

Then I'm creating in Scheduled tasks a new task which runs as "NT SYSTEM" account, the applications starts, but no GUI will shown on current logged on user.

Here an example of my code:

expandcollapse popup

#Region ;**** Directives created by AutoIt3Wrapper_GUI ****
#AutoIt3Wrapper_Icon=C:\temp\favicon.ico
#AutoIt3Wrapper_Outfile=C:\temp\User_Wait_Message_x32.exe
#AutoIt3Wrapper_Outfile_x64=C:\temp\User_Wait_Message_x64.exe
#AutoIt3Wrapper_Compression=4
#AutoIt3Wrapper_Compile_Both=y
#AutoIt3Wrapper_UseX64=y
#EndRegion ;**** Directives created by AutoIt3Wrapper_GUI ****
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

    GUICreate("Test...", 655, 475, -1, -1, BitOR($WS_MINIMIZEBOX, $WS_SYSMENU), $WS_EX_TOPMOST) ; alternativ zu $WS_CAPTION auch $WS_MINIMIZEBOX

    SoundPlay(@WindowsDir & "\media\Windows Balloon.wav", 1)

    $iOldOpt = Opt("GUICoordMode", 2)

    GUICtrlCreateLabel("''Test2''.", -1, 0, $widthCell)
    GUICtrlCreateLabel("Test3", -1, 0, $widthCell)
    GUICtrlCreateLabel("Test4", -1, 0, $widthCell)

    $cDummy = GUICtrlCreateDummy()
    Local $aAcc[1][2] = [["^{NUMPADMULT}", $cDummy]]
    GUISetAccelerators($aAcc)

    GUISetState() ; Zeigt eine leere Dialogbox an

    TraySetToolTip ("Test...")
    TrayTip ("Line 1", "Line 2", 15, 1)
    AutoItSetOption ("TrayMenuMode", 1)


    Do
        Until GUIGetMsg() = $cDummy
            Exit



    ;GUI starten, bis der Dialog beendet wird
    ;Ohne verhindern von Schließen via ALT + F4 bzw. STRG + PAUSE
    ;Do
    ;    $msg = GUIGetMsg()
    ;Until $msg = $GUI_EVENT_CLOSE

    $iOldOpt = Opt("GUICoordMode", $iOldOpt)
EndFunc   ;==>Example

 

How can I show the GUI by using Windows SYSTEM account?

 

Thanks a lot

Kind regards

can't, the SYSTEM account does not have access to the desktop.  if you want to see it, it has to be launched as the user.

Hello,

Thanks at all for feedback.
Sorry for late reply.

@BigDaddyO Yes, that's correct.

I resolved that problem by importing and starting a Scheduled Task and defined as user "predefined\Users", after that I delete directly the task => the message box still running.
If a User is logged on, it is also member of this group and in facts the user gets the message box. And if no one is logged on I don't care about that
Group ID of "predefined\Users" is: S-1-5-32-545
More information about groups:
https://support.microsoft.com/en-gb/help/243330/well-known-security-identifiers-in-windows-operating-systems

A Sample of a scheduled Task I've attached.
Import/Create task: SCHTASKS /CREATE /XML Scheduled_Task_Config.xml /TN "GUI_Application.exe" 2>&1
Start task: SCHTASKS /RUN /TN "GUI_Application.exe" 2>&1
Wait 5 seconds: PING 127.0.0.1 -n 6 >NUL 2>NUL
Delete task: SCHTASKS /DELETE /TN "GUI_Application.exe" 2>&1

If GUI Application is not required any more (e.g. installation finished), simply kill the application with all its sub-processes.
TASKKILL /IM "GUI_Application.exe" /T /F 2>&1

Maybe this is helpful for one or other

Kind regards
