Windows Powershell

Great tool for system admins.

Windows PowerShell is a new task-based command line shell and intuitive scripting language for system administration that provides comprehensive control and automation for Windows administrators.
The key features of Windows PowerShell include:
•One hundred and twenty nine standard utilities (called "cmdlets") for completing common system administration tasks such as working with the registry, services, processes, Windows Management Instrumentation, event logs, etc..
•Intuitive, task-based scripting language and support for existing scripts and command line tools..
•Designed for consistency so all tools and system data stores follow a common syntax, common naming conventions and information can be easily shared/piped between tools.
•Simplified command-based navigation of the operating system (including drives, startup files, and registry).
•Powerful object manipulation capabilities (objects can be directly manipulated or pipelined to other tools or databases).
•Designed for extensibility so that independent software vendors and enterprise developers can easily build custom tools and utilities to administer their software.
