The AT command is NOT fully compatible with jobs created by Scheduled Tasks.
In Windows 2000, Microsoft provided jt.exe to assist with command-line scheduling.
Windows XP has a built in command-line scheduler named schtasks.exe.
Schtasks supports creating, running, deleting, changing, terminating, and querying scheduled tasks.
To see the documentation, use Help and Support to search for schtasks.
To list verbose information about all scheduled tasks, open a CMD prompt and type:
schtasks /query /v /fo LIST
NOTE: The AT command is included for compatibility.
