Description of PowerShell-v3.0
Version 3.0 of Windows PowerShell, Microsoft's task automation and configuration management platform that functions as an interactive command shell and a scripting language. For general information about Windows PowerShell, see the Tag Info page for the powershell tag.
Availability
PowerShell 3.0 is included in Windows 8 and Windows Server 2012. It is available as a download for Windows 7 and Windows Server 2008 R2 with Service Pack 1 by installing either Windows Management Framework 3.0 or Microsoft .NET Framework 4.0 or 4.5 (PowerShell 2.0 is included in those versions of Windows).
Tag Usage
The powershell-3.0 tag should be used in conjunction with the powershell tag for questions that involve features that are specific to version 3.0. It is also acceptable, although not necessary, to add this tag to indicate which version you are working with even if the question is not necessarily specific to this version.
Regardless of whether the version-specific tag is included, the general powershell tag should be included in all PowerShell-related questions, as the version-specific tags have low visibility by themselves.
