Scheduled task in Windows Task Scheduler - part 3

This is the last part of Task Scheduler - security context which is created using New-ScheduledTaskPrincipal. Usually, we are using S4U logon type for any server scheduled task + Highest Run Level. S4U details as per MS documentation: Use an existing interactive token to run a task. The user must log on using a service for user (S4U) logon. When an S4U logon is used, no password is stored by the system and there is no access to either the network or encrypted files. You can find more information in this page:     https://docs.microsoft.com/en-us/windows/win32/taskschd/principal-logontype For any user ID that you specified to run the scheduled task, it requires "Log on as a batch job" or "Log on as a service".

Security context - any process must run in a valid security context. We can set the context using New-ScheduledTaskPrincipal. The following script creates an on demand task which requires user to manually trigger the task. $task_folder = "\myTasks\" $task_name = "myTask2" # this can be any Powershell script. $ps_script_file = "d:\temp5\test-script.ps1" ## The first line will show err if $task_folder does not exist. ## The second line will not...
