Check permissions required to run PowerShell scripts in Task Scheduler

Question

I would like to configure Task Scheduler to run a PowerShell script to install updates from Windows Update on my domain controllers and member servers.

Because the Task Scheduler's run account is a member of the domain's Backup Operators group, it does have permission to run the Task Scheduler.

However, even though the task scheduler is able to finish running, none of the PowerShell scripts seem to be running.

However, if you sign in as a member of the Administrators group of the domain, match the current directory to the location of the PowerShell script, change the script execution policy with Set-ExecutionPolicy, and execute it manually, the script will work as intended. I don't think there is a problem with writing the script itself.

Is the description to set the current directory in the PowerShell script insufficient?

Or am I missing permissions to run PowerShell scripts or install Windows Updates?

Thank you for your advice.

Hi,

Have you run the script manually as a Backup Operators group member? Sometimes it requires administrator rights to install updates. You can add the Backup Operators to the local administrators and see if the script in the task can run normally.
