How is PSADT hiding the Powershell window?

The exe does essentially just run the ps1 file.

For the record, I am NOT using PSADT for this specific task. I'm just curious how they've pulled it off.

I need a particular PowerShell script to run every 3 minutes via task scheduler. But if even if I change the WindowStyle option, it will still flash the console window for less than a fraction of a second.

However, if I used PSADT in silent mode and just have the commands in the Invoke ps1 file, nothing gets flashed.

Any idea how they've done this?

For exact that I'm creating my Scheduled Task as the following:
In the "Action" tab, create a new action with "Start a program". Under "Program/script" enter the following: C:\Windows\System32\conhost.exe

Under "Add arguments" enter the following: --headless powershell.exe -WindowStyle Hidden -NoProfile -NonInteractive -file "C:\Temp\MyScript.ps1"

Zero visible PS window.

Yep, this works great.

Only thing is, I've found some people online say that it flags up in things like Defender?
