I got an answer about this question, about 2 years ago,
but now I want to use the same command to create a task that will run every half an hour. How can that be done? Thank you in advance.

  • forgot to say: i use windows 7

  • Based on TechNet and Sample, it looks like that may not be supported by AT. AT allows specifying days, not minutes.

You should use schtasks instead:

schtasks /create /sc minute /mo 30 /tn "Task runs Every 30 Minuts" /tr c:\PATH\TO\TASK.exe


  • ok i'll check it

  • To create the task to run as the system account—something you can't do via the Scheduled Tasks GUI, but which happens automatically when you use the at command—use schtasks … /ru System ….
