How to schedule a one-time reboot via PS oneliner/function?

This is all that I have got.

$action = New-ScheduledTaskAction -Execute 'Powershell.exe' -Argument '-NoProfile -WindowStyle Hidden -command "& {Restart-Computer -Force -wait}"' $trigger = New-ScheduledTaskTrigger -Once -At 3am Register-ScheduledTask -Action $action -Trigger $trigger -TaskName 'ScheduledReboot' 

But this works once, then there is a task called “scheduledReboot” that won’t clear out. Is there a way to make this repeatable?
