Windows PowerShell is Microsoft’s task automation framework, consisting of a command-line shell and associated scripting language built on .NET Framework. In PowerShell, administrative tasks are generally performed by cmdlets (pronounced command-lets), which are specialized .NET classes implementing a particular operation. Sets of cmdlets may be combined together in scripts, executable (which are standalone applications), or by instantiating regular .NET classes.
By default, the execution of PowerShell scripts is disabled in Windows 7. This will prevent you from not only executing any of your own scripts, but also will prevent the Windows PowerShell Modules (located in Administrative Tools in the Control Panel) from working.
