Move Your Scheduled Tasks to Another PC

**Get-ScheduledTask** shows only real tasks with their path and state. Ignoring the \Microsoft\Windows tree avoids moving operating system jobs that belong to the installation.

Get-ScheduledTask | Where-Object TaskPath -notlike '\Microsoft*' |
  Select-Object TaskName,TaskPath,State | Sort-Object TaskPath,TaskName | Format-Table -AutoSize

The XML form is the only portable representation. **Export-ScheduledTask** writes it without the wrapper that schtasks adds when you redirect its output.

New-Item -ItemType Directory C:\TaskExport -Force | Out-Null
Get-ScheduledTask | Where-Object TaskPath -notlike '\Microsoft*' | ForEach-Object {
  Export-ScheduledTask -TaskName $_.TaskName -TaskPath $_.TaskPath |
    Set-Content -Path ("C:\TaskExport\{0}.xml" -f $_.TaskName) -Encoding UTF8
}
Get-ChildItem C:\TaskExport | Select-Object Name,Length

**UserId** under Principal and every absolute path in Arguments decide whether the task runs at all. A task bound to S-1-5-21-... on the old machine is bound to nothing on the new one.

Select-String -Path C:\TaskExport\*.xml -Pattern '<UserId>|<Command>|<Arguments>|<WorkingDirectory>' |
  Select-Object Filename,Line | Format-Table -Wrap

**Register-ScheduledTask -Xml** restores triggers, conditions and actions. **-User** overrides the stale principal, and **-RunLevel Highest** keeps an elevated task elevated.

$xml = Get-Content C:\TaskExport\NightlyBackup.xml -Raw
Register-ScheduledTask -TaskName 'NightlyBackup' -TaskPath '\' -Xml $xml -User 'SYSTEM' -RunLevel Highest
Get-ScheduledTask -TaskName 'NightlyBackup' | Select-Object TaskName,State,@{n='User';e={$_.Principal.UserId}}

A task that registers can still fail on its first run. **Get-ScheduledTaskInfo** returns LastRunTime, LastTaskResult and the next run, and 0x0 is the only success value.

Start-ScheduledTask -TaskName 'NightlyBackup'
Start-Sleep -Seconds 10
Get-ScheduledTaskInfo -TaskName 'NightlyBackup' | Select-Object LastRunTime,LastTaskResult,NextRunTime,NumberOfMissedRuns

**0x2** means the file or path does not exist, **0x41303** means the task never ran. Both are path or trigger problems, not permission problems, and both are visible in the task's history.

Get-WinEvent -LogName 'Microsoft-Windows-TaskScheduler/Operational' -MaxEvents 20 |
  Where-Object Id -in 102,201,203 | Select-Object TimeCreated,Id,Message
Enable-ScheduledTask -TaskName 'NightlyBackup'
