Back to the top

Windows PowerShell 1.0 is a new task-based command-line shell and scripting language that is designed specifically for system administration. Built on the Microsoft .NET Framework, Windows PowerShell helps IT professionals and power users control and automate the administration of the Windows operating system and the applications that run on Windows.

By using Windows PowerShell, administrators can manage their systems by typing individual commands or by running scripts that automate management tasks. Microsoft Exchange Server 2007, Microsoft System Center Operations Manager 2007, System Center Data Protection Manager V2, and System Center Virtual Machine Manager use Windows PowerShell to improve efficiency and productivity.

Windows PowerShell includes the following:

•	One hundred and twenty-nine standard utilities ("cmdlets") for performing common system administration tasks, such as managing the registry, services, processes, and event logs, and for using Windows Management Instrumentation.
•	A task-based scripting language and support for existing scripts and command-line tools.
•	Consistent design. Because Windows PowerShell utilities ("cmdlets") and system data stores use common syntax and naming conventions, data can be shared easily. The output from one utility can be used as the input to another utility without reformatting or manipulation.
•	Simplified, command-based navigation of the operating system lets users browse the registry and other data stores by using the same techniques that they use to browse the file system.
•	Powerful object manipulation capabilities. Objects can be directly manipulated or sent to other tools or databases.
•	Extensible interface. Independent software vendors and enterprise developers can build custom tools and utilities to manage their software.
