Also, I thought requiring a person to be logged on was dependent on options you chose when creating the scheduled task?

It is, and thus the point of me attempting to figure out how to specify a user rather than a group via powershell.

Doing it via the gui is simple, it's trying to do it via powershell that has me hung up.

Hrmm. . .

I wonder if New-ScheduledTaskPrincipal -UserID 'localhost\user' would work. . . but what would I use to pass in the password. . .

Why are you running it as a specific user instead of SYSTEM ?

For some unknown to me reason running as a system task was failing. . .

[DustinB3403]

Oh I know why now. . .

Rather than actually running the powershell script (task scheduler) it is launching notepad to attempt to open the ps1 file.

This obviously is a failure.

What needs to execute is "powershell.exe" with arguments -ExecutionPolicy Bypass c:\Scripts\choco-upgrade.ps1

[DustinB3403]

Which maybe (can't recall if I tried this. . .) just doing

-execute 'powershell.exe' -arguments '. .. . ' will work. .

[DustinB3403]

Nope that fails. . . -Arguments isn't a known parameter

[DustinB3403]

This here says I should be using New-ScheduleTaskAction with -execute and -argument

but it fails.. . .

[DustinB3403]

doh. . . it would help if I didn't fatfinger the spelling of "Argument". . .

So using the SYSTEM account appears to work, at least when I manually run the task. So meh w/e. It still requires a user to be logged in, which I might see if I can change that flag as I don't want to rely on my users remaining logged in.

But they likely never sign out either.

I know this post is old, but I've found doing scheduled tasks with SaltStack is insanely simple and very effective lately... so much more than using MS Group Policy.

You can, in theory, use it to report and manage Windows Defender.

Here's an example of a task that goes to all minions it's supposed to go to... and it "just works". No AD required.
Also, using SaltStack to sync that .ps1 it runs from GitLab:
