schtasks delete

Deletes a scheduled task from the schedule. This command doesn't delete the program that the task runs or interrupt a running program.

Syntax

schtasks /delete /tn {<taskname> | *} [/f] [/s <computer> [/u [<domain>\]<user> [/p <password>]]]

Parameter	Description
/tn `{<taskname> \| *}`	Identifies the task to be deleted. If you use the `*`, this command deletes all tasks scheduled for the computer, not just the tasks scheduled by the current user.
/f	Suppresses the confirmation message. The task is deleted without warning.
/s `<computer>`	Specifies the name or IP address of a remote computer (with or without backslashes). The default is the local computer.
/u `[<domain>]`	Runs this command with the permissions of the specified user account. By default, the command runs with the permissions of the current user of the local computer. The specified user account must be a member of the Administrators group on the remote computer. The /u and /p parameters are valid only when you use /s.
/p `<password>`	Specifies the password of the user account specified in the /u parameter. If you use the /u parameter without the /p parameter or the password argument, schtasks will prompt you for a password. The /u and /p parameters are valid only when you use /s.
/?	Displays help at the command prompt.
