PowerShell 3.0 for Windows 7
Microsoft has released version 3.0 of its Windows Management Framework. Among its components is PowerShell 3.0, the same version that is also part of Windows 8 and Server 2012. Microsoft says that it has simplified the built-in scripting language syntax and also made it easier to find and run installed modules.
The Integrated Scripting Environment (ISE) add-on allows users to explore the approximately 1,000 built-in commands via a command list, which can be searched and filtered. Scripts can be executed as scheduled jobs that start either at a given time or in response to an event. Using the OData IIS Extensions, PowerShell commands can be turned into a RESTful web service that is accessible through an OData (Open Data Protocol) interface, allowing the commands to be invoked using HTTP(S).
As well as the new PowerShell, Windows Management Framework 3.0 also includes a new version of Windows Management Instrumentation (WMI) that is designed to simplify the programming of WMI providers and offers a new management API for non-Windows computers. Additionally, the remote management connections of WinRM (Windows Remote Management) are now said to be more robust and more standards compliant.
Windows Management Framework 3.0 can be installed under Windows 7 with Service Pack 1 and under Windows Server 2008 with SP 2, as well as Server 2008 R2 with SP 1. Separate installation packages are available for the 32- and 64-bit versions of each operating system.
