I am using Windows PowerShell 1.0 in Windows Server 2008 R2. I have tried PowerShell 3.0 in Windows 8 and it looks good to me.

Now the question is: How I can upgrade PowerShell on the Windows Server 2008 R2 machine? If 3.0 is not available for me, then is there any way to upgrade to the latest available version?

Name             : ConsoleHost
Version          : 2.0
InstanceId       : f0b6480c-be55-429d-a197-65604de5887e
UI               : System.Management.Automation.Internal.Host.InternalHostUserInterface
CurrentCulture   : en-US
CurrentUICulture : en-US
PrivateData      : Microsoft.PowerShell.ConsoleHost+ConsoleColorProxy
IsRunspacePushed : False
Runspace         : System.Management.Automation.Runspaces.LocalRunspace

That's impossible. Windows PowerShell 2.0 is included in Windows Server 2008 R2. You cannot install Windows PowerShell 1.0 in 2008 R2 in any supported fashion.

To verify the version of PowerShell you're running, simply echo the $host variable.

Name             : Windows PowerShell ISE Host
Version          : 3.0
InstanceId       : 711f19be-3f19-4612-bea3-61899c1a73c2
UI               : System.Management.Automation.Internal.Host.InternalHostUserInterface
CurrentCulture   : en-US
CurrentUICulture : en-US
PrivateData      : Microsoft.PowerShell.Host.ISE.ISEOptions
IsRunspacePushed : False
Runspace         : System.Management.Automation.Runspaces.LocalRunspace

I think you are confused. Windows Server 2008 R2 SP1 includes Windows PowerShell 2.0 out of the box. – Trevor Sullivan Jul 1 '12 at 21:33
yes I am confused with it's path %SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe. – Gupta Anirudha Jul 1 '12 at 21:38

Yup, you got it - the path still says v1.0. Ignore that :) – Trevor Sullivan Jul 1 '12 at 23:44

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 http://go.microsoft.com/fwlink/?LinkID=212547.

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

  4. Install Windows Management Framework 3.0 from the Microsoft Download Center at http://go.microsoft.com/fwlink/?LinkID=240290.

The page also describes how to install PowerShell 3.0 on Server 2008 (non-R2) and Windows 7.
