Notes:
For MONTHLY schedules give the DAY as a number 1 – 31 (default=1)

To prompt for the password, specify /RP * or /RP none
The User Account under which the Schedule service runs may require specific file access permissions, user permissions and drive mappings.
If the /RU username and /RP Password parameters match the currently logged-in user, the task will run interactively (visible in the foreground).

For the system account, /RU username can be written as “”, “NT AUTHORITY\SYSTEM” or “SYSTEM”, a Password is not required. The system account has full access to the local machine but has no permissions on any other machines (or mapped drives) across the Network.
/SC schedule The schedule frequency.
Valid schedules: MINUTE,HOURLY,DAILY,WEEKLY,MONTHLY, ONCE,ONSTART,ONLOGON,ONIDLE.

/MO modifiers allow finer control:

MINUTE: 1 – 1439 minutes.
HOURLY: 1 – 23 hours.
DAILY: 1 – 365 days.
WEEKLY: 1 – 52 weeks.
ONCE: No modifiers.
ONSTART: No modifiers.
ONLOGON: No modifiers.
ONIDLE: No modifiers.
MONTHLY: 1 – 12, or FIRST, SECOND, THIRD, FOURTH, LAST, LASTDAY.
Power Saving
The property for “Wake up the machine to run this task” cannot be set using schtasks, but this property is essential if you need the task to run on a machine that has PowerSaving enabled.
To work around this, create a task on one computer using the control panel GUI. This will create a .job file in C:\%windir%\Tasks\
To replicate the scheduled task onto other machines copy the .JOB file to C:\%windir%\Tasks on each machine.

This techique will not retain any system account credentials, so if you need to run the tasks under System, run the following after copying the .JOB file:
SCHTASKS /CHANGE /RU “NT Authority\System” /TN “Yourtaskname”
Examples:
Create a task to run at 11 pm every weekday
SCHTASKS /Create /SC weekly /D MON,TUE,WED,THU,FRI /TN MyDailyBackup /ST 23:00:00 /TR c:\backup.cmd /RU MyDomain\MyLogin /RP MyPassword
Now delete the task:
SCHTASKS /Delete /TN “MyDailyBackup” /f
Create a daily task to run a script at 5 pm:
SCHTASKS /create /tn “My Script” /tr “\”c:\my folder\script.cmd\” arguments” /sc daily /sd 12/29/2008 /st 17:00
Task Scheduler options are stored in the registry
HKLM\SOFTWARE\Microsoft\SchedulingAgent\
