The at command is an old command that avaiable since Windows 2000 (correct me if I wrong), you can create remote tasks with this command. And best part from at command is it has simple parameters. Just put some parameters with it and then a task will created. On other side with schtasks command you can create complex tasks but maybe you can confused with its parameters that so complicated.
OK, first we will learn about at command.

1. To use at command, open your command console first via Start -> Run menu and then type cmd in textbox or via Start -> All Programs -> Accessories -> Command Prompt.
2. At prompt type at /? if you want get some help from at command.
3. To create a remote task, just type at \\server 6pm /every:sunday "winword.exe", we can learn from that command parameters, \\server is your remote computer, 6pm is the time that the task will ran, /every:sunday is day parameter and last “winword” is task will ran.

5. To delete a task, type at 2 /delete, number 2 is id task you can look it with typing at at your prompt (point 2), /delete is parameter to delete a task. To delete entire tasks, type at /delete.
   
6. Almost forgeted, if you want create a local task, just type at 6pm /every:sunday "test.bat", you can look the explaining in point 3.
   

Now, I want discuss about schtasks command.

1. To create a task with schktaks command, type schtasks /create /ru system /sc weekly /d fri /tn "Remain me to make report" /tr "excel.exe" /st 19:00:00. And this is the explanation from that command; /create is parameter to create task, /ru is parameter to set user that run this task, /sc is paremeter to defines frequency the task will ran you can choose MINUTE, HOURLY, DAILY, WEEKLY, MONTHLY, ONCE, ONSTART, ONLOGON, ONIDLE for parameter value, /d is day to run, /tn is parameter to task name, /tr is parameter to set task to run, /st is parameter to start to run.
   
2. To display all run tasks type schtasks at prompt.
   
3. To display all tasks that have been created with at command or schtasks command you can display it with Scheduled Tasks software that run in GUI mode. To open it click Start – All Programs – Accessories – System Tool - ,
   
   and look what happend with your all tasks in there.
   
4. And to delete task with schtasks command, type schtasks /delete /tn "Remain me to make report" /F, /tn fill with your task name, /f parameter is parameter to forces the utility to delete the task and suppress any warnings when the task is currently running.
   
5. To display all schtasks parameter type schtasks /? or if you want detail about /delete parameter or else, type schtasks /delete /? at your prompt.

I hope your job to scheduling your task will be more easier.
