Scheduled task inventory and failure report

Good For

• job failure triage
• maintenance task review
• server migration prep
• owner cleanup
• automation reliability

How to Use It

1. Collect all scheduled tasks from the target host or host list and preserve path, state, and author.
2. Capture run metadata for important tasks, including last run time, last result, next run time, and missed runs.
3. Review Task Scheduler operational events around failures before changing credentials, triggers, or actions.
4. Flag disabled tasks, unknown owners, repeated nonzero results, and tasks with stale run history.
5. Map business-critical tasks to owners and recovery expectations.
6. Export the inventory for follow-up instead of enabling, disabling, or editing tasks during discovery.

Command Starter

Safe to run: read-only

# ---------------------------------------------------------------------
# Scheduled task inventory starter
# ---------------------------------------------------------------------
$OutputPath = '.\scheduled-task-inventory.csv'

$Results = foreach ($Task in Get-ScheduledTask) {
    # Runtime metadata is queried per task so the inventory and execution state stay aligned.
    $Info = Get-ScheduledTaskInfo -TaskName $Task.TaskName -TaskPath $Task.TaskPath -ErrorAction SilentlyContinue

    [pscustomobject]@{
        TaskName            = $Task.TaskName

        State               = $Task.State
        Author              = $Task.Author
        LastRunTime         = $Info.LastRunTime
        LastTaskResult      = $Info.LastTaskResult
        NextRunTime         = $Info.NextRunTime

Validation

• Every scoped host has a task inventory or an access/error note.
• Failed and disabled tasks are classified by owner, business impact, and next action.
• Any later task change has before-state evidence and a rollback plan.

Reporting

• export scheduled task inventory and run results to CSV
• attach recent Task Scheduler operational events to incident or maintenance tickets
• promote repeated use into an automation reliability report

Safety Notes

• This inventory is read-only and should not enable, disable, start, stop, or edit tasks.
• Do not change task credentials or triggers without owner approval and rollback evidence.
