'Windows Powershell', and 'Microsoft Script Center'

Windows Powershell

From Microsoft. Using a new admin-focused scripting language, more than 130 standard command line tools, and consistent syntax and utilities, Windows PowerShell allows IT Professionals to more easily control system administration and accelerate automation. Windows PowerShell is easy to adopt, learn, and use, because it works with your existing IT infrastructure and existing script investments, and because it runs on Windows XP, Windows Vista, Windows Server 2003 and Windows Server "Longhorn". Exchange Server 2007, System Center Operations Manager 2007, System Center Data Protection Manager V2, and System Center Virtual Machine Manager leverage Windows PowerShell to improve efficiency and productivity.
