Windows Task Scheduler is a utility that helps to execute any process periodically. For example, you want to sync your working files on a daily basis, scan a virus, process some data, etc.

A task has the following components:

The following script creates an on demand task which requires the 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 show any error if $task_folder does not exist.
#$exist = Get-ScheduledTask -TaskPath $task_folder | Where-Object {$_.TaskName -eq $task_name}

$exist = Get-ScheduledTask | where {$_.TaskPath -eq "\myTasks\" -and $_.TaskName -eq $task_name }

if (!$exist)  {        
    $axn = New-ScheduledTaskAction -Execute "powershell.exe" -Argument "-ExecutionPolicy Bypass ""$ps_script_file"""

    Register-ScheduledTask -TaskName $task_name  -TaskPath $task_folder -Action $axn

    Write-Host "created new task"
else {
    Write-Host "The task already exists"

The contents of test-script.ps1

$dt = (get-date).ToString()
Set-Content -Path "d:\temp5\test-ps-output.txt" -Value $dt
