Problems with Windows Task Scheduler - windows

I have two problems with Windows Task Manager:
One, I have a Python script that sends an email notification, through gmail, at the end of the run. This works fine when I run the script itself, but when I run the script through Windows Task Scheduler, the script runs fine, but does not send an email. Why would this happen?
Two, when running the same script through task scheduler on a remote desktop, when I am logged in, but my session is closed, firefox will not open.
Any help would be appreciated, thank you.

The Task manager doesn't display any GUI for the current user.
You need to be login as system.

A similar thing happened with me ( while using PHP ) and I found out the reason that I had put a relative path to a file to be included in the code.
include("./lib/libfile.php");
Later when I replaced it with the absolute path it worked all right.
include("D://code/lib/libfile.php");
You might have a similar problem.

It could be that you need to specify where it starts in. This is important if you make local references in your program. This would also result in your program running fine, but not doing everything it is built to do.
Inside task scheduler, see "Actions", then edit an action. It's the parameter it says is optional.

Make a PowerShell script run on startup in the OOBE Sysprep environment

Thanks for stopping by, I've searched the corners of the internet but haven't gotten anywhere.
To provision devices for my organization, we must manually run PowerShell commands using SHIFT + F10 in the Windows 11 OOBE as we have multiple methods, one of which being legacy. I'm sure there are better methods but I'm unfortunately working within these limitations. So far, to automate the imaging process, I've created an autounattend.xml which makes WinPE completely silent and some pages of the OOBE also.
Recently, I combined all the PowerShell commands we had been running prior into a script that, after running repeated checks for a network connection, prompts users with a GUI and effectively automates everything we had been doing manually before:
Message box with radio buttons
I need to make this run when the OOBE Sysprep starts, but I really need some help.
The script contains GUI, so it cannot run silently and the user needs to interact with it.
The script must start with the OOBE Windows Welcome Screen, (i.e. select region screen). This is a limitation of the modules used and I therefore can't include it as a synchronous command in FirstLogonCommands or include it in SetupComplete.cmd, as those both execute after the OOBE is completed.
I've tried configuring the answer file to boot into audit mode and have the script run there, but the script requires several reboots and I get an installation failed message after any reboot (despite later making the script enable the Administrator account and call "sysprep /audit /reboot"). Additionally, the Audit Administrator account takes ~15 minutes to log in so it defeats the whole purpose of time saving.
I've tried using Task Scheduler, running both on System Start Up and User Log On, as defaultuser0, BUILTIN\Administrators and SYSTEM. Task scheduler seems to either queue tasks or not call them at all in the OOBE
I've tried placing the script, and then a shortcut of the script, in the common start up folder but that didn't work either.
To reiterate, I need a way to automatically run a script when the OOBE Sysprep starts. Furthermore, I need it to run every time the OOBE is launched as sometimes, we have to manually reboot if something glitches or goes wrong so the script will need to run again when the OOBE is resumed.
I know this is a tough one due to the limitations, but this will make the device rollout significantly easier.
Thanks,
Jake

Windows Task Scheduler not running task despite trigger

please keep in mind throughout this that I am quite new to windows automation and powerShell so go easy on me please. My goal was to create an automatic USB cloner in order to copy files if the drive has a specific name. I've sorted the copying and the name thing in powerShell and batch. Now remember the goal is to have the script running 24/7, based on a lot of reading up on this it would seem that Windows Task Scheduler is the Ideal way to do this. So I set up a task where the action is running the powerShell and the trigger is "At log on of any user" (I am the only user anyway). This is all well and good however when I log off and back in to test it, It doesn't work. I investigated and it turns out in Task Scheduler, for the usbClone task the status says "Ready" as opposed to "Running" (which is what it should be). Also I have ticked the "Enabled" button on the trigger. For reference my OS is Windows 10. If there is a flaw in my logic (I wouldn't be surprised) please explain, other than that it should be a simple "run this script on log on" task yet it isn't working. I should also point out that if I manually right click the task and click "Run" it runs just fine. Any help would be much appreciated
EDIT: Please read comments to see what steps I have already taken based on suggestion.
Thanks in advance,

Running VBScript through task scheduler while computer is locked

I have a script that loads an excel file from some link, and then writes some information from the excel file to a text file. I set up a task on Task Scheduler to run the script and then email the text file, and it works fine while logged on. It does not, however, run while the computer is locked.
Unfortunately, I need the task to be run in the early morning before I get to work. Is there any way to make this work?
Unfortunately I don't think this is possible. This link HERE contains someone with a similar situation that was solved by making the computer "lock" via custom vbscript. However this is not the traditional "Lock" of a computer and actually just disables and removes a bunch of things... Further down they mention it being possible but it's very limited on what can happen... and making windows active is one of the limitations.

Task Scheduler WorkItem Not Running

I have a very specific problem that I need fixing. The major issue is that I don't exactly know how to properly search the remnants of my problem on google. Therefore I am coming to StackOverflow for advice in hopes that someone will assist me.
Summary
So I am writing an application which is to be PCI-compliant for the company which I am starting. The application involves IPC (Inter-process communication) and two "watch-dog" apps which monitor the status of the main application. One of these "watch-dog" applications is an updater (sends an HTTP Request to the server looking for updates of the application).
So! This method which I am using to check the server if the application is up-to-date is using the WinInet library and InternetOpen() to send the request. Then read the response of the page and use GetCookie() to store the response in a buffer. It shall then parse the response accordingly.
If the response says that the current version of my application is less than the version located on the server. It will then tell the customer (user) that their application is out of date, and ask them whether or not they want to update the software. If they choose to update the software, it will perform a Download And Execute from the internet and launch the update-installer on the user's PC.
The Problem
Unfortunately, windows is very "secure" when it comes to having an "unauthorized" application send an HTTP Request to an outgoing url, let alone download something from the server then execute it on the users PC.
My conclusion to this issue was to add the watch-dog programs to the Task Scheduler. That way after the main application is run, it will spawn the watch-dog programs and check if they are running with NTAUTHORITY privileges (which are granted by the Task Scheduler).
After implementing the code to create the task and point it to the location of the watch-dog programs, naming it, writing a description and everything. I executed the program. It ran without errors though here the REAL PROBLEM:
1) Programs executes
2) Spawns watch-dog programs
3) Watchdog program checks for new version
4) Version is found
5) Installer is downloaded, execute ... but
6) The installer does not appear on the screen!
When I run my 'Process Hacker' application to monitor all process actions. I can see that the new installer is download & executed. It is running as NTAUTHORITY/SYSTEM just like the watch-dog programs but it doesn't appear on the system.
I made sure that in my code the status of the window is set to SW_SHOWNORMAL not SW_HIDE. I also made sure that all flags are set accordingly. Though it doesn't appear on the screen!
When I run the application without adding it to the Task Scheduler as my user without NTAUTHORITY/SYSTEM status and just regular user status. It executes (obviously since I am already running as administrator) -- everything works fine. But after adding it to Task Scheduler and having it run with SYSTEM level privileges. The window doesn't appear on the screen visually. Why's that?
I would greatly appreciate anyone that is able to assist me with this problem. Thank-you!
edit 1
Can anyone help me understand how this user applied his fix in the registry? By reading the problem I can somewhat interpret that he had the same issue as me.
App is invisible if started from Task Scheduler without any user logged in
In any case, I am trying to use the advice that Gisley gave me to run the application in Interactive Mode. Possibly going to try to give that a try. Still looking for more answers but I am going to be working no this none-the-less in the meantime.
edit 2
I tried setting the INTERACTIVE FLAG and it had no effect unfortunately.
Allow me to just emphasize my problem:
For example I write a program which has message boxes and put it in a loop.
for
message box
get current pid
make process in the task scheduler
spawn new process as the task scheduler proc with NTAUTHORITY/SYSTEM
kill last proc pid
end for
Then when I execute it:
I get the message box. Then after new process opens with NTAUTHORITY/SYSTEM the message box does not appear anymore.
Same for if I open a calculator for example.
System("cmd.exe start /c calc.exe")
Program runs... opens calculator
Program gets NTAUTHORITY/SYSTEM status
ON the next loop it executes the calc.exe
I see it in my task manager but it doesnt appear on the screen
I hope the above helped emphasize the core of my issue. I dont see the processes opened by the task scheduler process id with NTAUTHORITY/SYSTEM rights... I dont see the procs executed by it on my screen, though I see them in the task manager | process hacker and they are running with NTAUTHORITY/SYSTEM privileges too.
A shot in the dark - try running the task in interactive mode, but you'll need to have a user logged on.

Alternatively, or additionally, pass parameters to the installer so that it installs silently.

VB6 program when run as schedule task freezes until focused

I have been searching the web for an answer however came up with nothing. I created a VB program that calls a .bat script to call commands to run a WinSCP script. This WinSCP script simply transfer files from a sftp (linux) server to a windows machine. When running the program either via VB6 IDE or as a compiled executable the program run as normal.
However when running the program as a schedule task the program freezes and only runs until focus is brought to it. Have any encountered this error? (I'm running win 7 32bit)
There was a question similar to mine that was asked here however about VBScript and it seems the person was able to pin point the line causing the issue, not the same for me. Here is the link to the thread vbs runs by double clicking, freezes when run from task scheduler
Thanks in advance,
j3rg
I have found what was causing the error to occur. My project consist of a form and a module. I call the form via the module in the manner:
form.show
I forgot to set in the properties of the project to have the program start from the module Sub Main sub-routine. After selecting this option the program work as normal when called by a schedule task.
I hope this information help anyone that runs into the same scenario.
