SPJeff

One time SharePoint timer jobs can often get “stuck” and fail to execute.   Clearing them all out manually in Central Admin is tedious.  PowerShell below will remove all “One-time” jobs with a one liner. Cheers.  

PowerShell Code

Get-SPTimerJob |? {$_.Schedule.GetType().ToString() -eq "Microsoft.SharePoint.SPOneTimeSchedule"} | % {$_.Delete()}
