/End Stops the currently running scheduled task.
/ShowSid Shows the security identifier corresponding to a scheduled task name.

SCHTASKS /Create [/S system [/U username [/P [password]]]] [/RU username [/RP password]] /SC schedule [/MO modifier] [/D day] [/M months] [/I idletime] /TN taskname /TR taskrun [/ST starttime] [/RI interval] [ {/ET endtime | /DU duration} [/K] [/XML xmlfile] [/V1]] [/SD startdate] [/ED enddate] [/IT | /NP] [/Z] [/F] [/HRESULT] [/?]

/S system Specifies the remote system to which it should connect. If omitted, the system parameter defaults to the local system.
/U username Specifies the user context under which SchTasks.exe should execute.

/RP [password] Specifies the password for the "run as" user. To prompt for the password, the value must be either "*" or none. This password is ignored for the system account. Must be combined with either /RU or /XML switch.
/SC schedule Specifies the schedule frequency. Valid schedule types: MINUTE, HOURLY, DAILY, WEEKLY, MONTHLY, ONCE, ONSTART, ONLOGON, ONIDLE, ONEVENT.
/MO modifier Refines the schedule type to allow finer control over schedule recurrence. Valid values are listed in the Modifiers section below.
/D days Specifies the day of the week to run the task. Valid values: MON, TUE, WED, THU, FRI, SAT, SUN and for MONTHLY schedules 1 - 31 (days of the month). Wildcard "*" specifies all days.

/ST starttime Specifies the start time to run the task. The time format is HH:mm (24 hour time) for example, 14:30 for 2:30 PM. Defaults to current time if /ST is not specified. This option is required with /SC ONCE.
/RI interval Specifies the repetition interval in minutes. This is not applicable for schedule types: MINUTE, HOURLY, ONSTART, ONLOGON, ONIDLE, ONEVENT. Valid range: 1 - 599940 minutes. If either /ET or /DU is specified, then it defaults to 10 minutes.
/ET endtime Specifies the end time to run the task. The time format is HH:mm (24 hour time) for example, 14:50 for 2:50 PM. This is not applicable for schedule types: ONSTART, ONLOGON, ONIDLE, ONEVENT.

/IT   Enables the task to run interactively only if the /RU user is currently logged on at the time the job runs. This task runs only if the user is logged into the computer.
/NP   No password is stored. The task runs non-interactively as the given user. Only local resources are available.
/Z   Marks the task for deletion after its final run.
/XML xmlfile Creates a task from the task XML specified in a file. Can be combined with /RU and /RP switches, or with /RP alone, when task XML already contains the principal.
/V1   Creates a task visible to pre-Vista platforms. Not compatible with /XML.
/F   Forcefully creates the task and suppresses warnings if the specified task already exists.
/RL level Sets the Run Level for the job. Valid values are LIMITED and HIGHEST. The default is LIMITED.
/DELAY delaytime Specifies the wait time to delay the running of the task after the trigger is fired. The time format is mmmm:ss. This option is only valid for schedule types ONSTART, ONLOGON, ONEVENT.
