##some examples how to run PS direct command in win task scheduler

##run in admin shell
##simple style
$Trigger = New-ScheduledTaskTrigger -Daily -At "10:15pm"  # Specify the trigger settings

$User = "NT AUTHORITY\SYSTEM" # Specify the account to run the script

$Action = New-ScheduledTaskAction -Execute "PowerShell.exe" -Argument '-Command Get-ChildItem C:\myapp\config\tmp -Recurse | Where LastWriteTime -lt  (Get-Date).AddDays(-2) | Remove-Item -Recurse -Force 2>&1 > C:\myapp\logs\ps-script-out.log' # Specify what program to run and with its parameters


Register-ScheduledTask -TaskName "myappcleanup-tmp-dir1" -Description "myapp cleanup of tmp directory" -Trigger $Trigger -User $User -Action $Action  #consider -RunLevel Highest  # Specify the name of the task

##end



##base64 way
$command = '-Command Get-ChildItem C:\myapp\config\tmp -Recurse | Where LastWriteTime -lt  (Get-Date).AddDays(-2) | Remove-Item -Recurse -Force 2>&1 > C:\myapp\logs\ps-script-out.log'
$bytes = [System.Text.Encoding]::Unicode.GetBytes($command)
$encodedCommand = [Convert]::ToBase64String($bytes)

$Trigger = New-ScheduledTaskTrigger -Daily -At "10:15pm"  # Specify the trigger settings

$User = "NT AUTHORITY\SYSTEM" # Specify the account to run the script

$Action = New-ScheduledTaskAction -Execute "PowerShell.exe" -Argument "-NoProfile -EncodedCommand $encodedCommand" # Specify what program to run and with its parameters

Register-ScheduledTask -TaskName "myappcleanup-tmp-dir2" -Description "myapp cleanup of tmp directory" -Trigger $Trigger -User $User -Action $Action  -RunLevel Highest # Specify the name of the task
##base64 end


##ps job style, create a Win Task scheduler with a wrapper. seems odd. 
$PSTrigger = New-JobTrigger -Daily -At "10:15pm"
Register-ScheduledJob -Name "myappcleanup-tmp-dir3" -Trigger $PSTrigger -ScriptBlock {
Get-ChildItem C:\myapp\config\tmp -Recurse | Where LastWriteTime -lt  (Get-Date).AddDays(-2)  | Remove-Item
}

##check job
Get-ScheduledJob

##delete with 
 Get-ScheduledJob myappcleanup-tmp-dir3 | Unregister-ScheduledJob

Register-ScheduledJob creates a Win Schedule Task with that parameter:

-NoLogo -NonInteractive -WindowStyle Hidden -Command "Import-Module PSScheduledJob; $jobDef = [Microsoft.PowerShell.ScheduledJob.ScheduledJobDefinition]::LoadFromStore('myappcleanup-tmp-dir3', 'C:\Users\tilos\AppData\Local\Microsoft\Windows\PowerShell\ScheduledJobs'); $jobDef.Run()"
