When Unregister-ScheduledJob deletes or "unregisters" a scheduled job, it deletes the directory for the scheduled job ( $home\AppData\Local\Microsoft\Windows\PowerShell\ScheduledJobs), which contains the XML file that defines the scheduled job, the job execution history, and all job results. This action also deletes the job from Task Scheduler.

Unregister-ScheduledJob deletes only the scheduled jobs that are created by using Register-ScheduledJob . It does not delete scheduled jobs that are created in Task Scheduler.

Use the parameters of Unregister-ScheduledJob to delete scheduled jobs by ID or name, or pipe scheduled jobs from Get-ScheduledJob to Unregister-ScheduledJob.

Examples

Delete the scheduled job called SS64Job:

C:\PS> Unregister-ScheduledJob SS64Job

Delete all (PowerShell) scheduled jobs:

C:\PS> Get-ScheduledJob | Unregister-ScheduledJob -Force

Delete a scheduled job on a remote computer:

PS C:\> Invoke-Command -ComputerName Server64 { Unregister-ScheduledJob -Name SS64*}
