VBScript Programmer's Reference, Third Edition

Chapter 12. Task Scheduler Scripting

The Windows Task Scheduler allows the user or administrator to schedule a program to be run at a particular time or in response to a specific event. Task Scheduler can also be controlled via script. Windows Vista and Windows Server 2008 ship with the new redesigned Task Scheduler 2.0 and in this chapter you'll see the changes made to Task Scheduler and how to make use of it. Here are some of the new features and capabilities:

• Sends automatic email notifications when there are problems with the local or remote system

• Launches new diagnostic programs when a problem with Task Scheduler or a scheduled task is detected

• Can execute tasks when the PC is unattended

• Offers the ability to run tasks in a particular sequence

• Carries out actions based on an event logged in the system event log

• Configures systems to automatically respond to system problems

• Runs tasks in response to system changes of multiple triggers

• Configures a system to wake up from standby or hibernation so that routine tasks can be carried out

Task Scheduler 2.0 also includes new tools and features, such as:

• Triggers and actions

• Credential management

• Improved user interface

• MMC snap-in

• Task settings

• Improved scripting support

• Task Scheduler XML schema
