PowerShell 2.0 is included with Server 2008 R2. PowerShell 3.0 is included with Windows 8 and Server 2012. PowerShell 3.0 can be installed on Server 2008 R2.

The following instructions are excerpted from this page: http://technet.microsoft.com/en-us/library/hh847837.aspx

  1. Before installing Windows Management Framework 3.0, uninstall any previous versions of Windows Management Framework 3.0.

  2. Install the full installation of Microsoft .NET Framework 4.0 (dotNetFx40_Full_setup.exe) from the Microsoft Download Center at https://go.microsoft.com/fwlink/?LinkID=212547.

  3. Or, install Microsoft .NET Framework 4.5 (dotNetFx45_Full_setup.exe) from the Microsoft Download Center at https://go.microsoft.com/fwlink/?LinkID=242919.
